| Topic 2: Strategic opportunities for decarbonization of the chemicals industry through biocatalysts | Background
SNL has developed various chemical, biological, and integrated technologies for the manipulation of abundant biopolymers (e.g., lignin) through several stand-alone or collaborative projects including Co-Optima, JBEI, ABF, among others.
Interest
SNL is committed to DOE’s SAF Grand Challenge and Industrial Decarbonization efforts. Accordingly, SNL’s interests towards the realization of sustainable biomanufacturing and bioeconomy includes producing SAF and other chemicals from underutilized natural abundant resources or domestic/agricultural/industrial residues. SNL has developed chemical and biochemical technologies to convert these residues into bioavailable intermediates, and subsequent downstream conversion of these intermediates into platform molecules.
Capabilities
SNL has developed the following lignin conversion technologies that can accelerate the decarbonization of the chemicals industry through biocatalysts, for instance,
1. Enzyme-mediated detoxification of stream obtained after reductive catalytic fraction of lignin into selective bioavailable and industrially-relevant platform molecules/intermediates including vanillin, syringic acid, etc.
2. Mild catalytic conversion of lignin into bioavailable carboxylic acids with carbon numbers in the range 1-4 or in the range 6-9.
3. Conversion of lignin into bioavailable alcohol- and carboxylic acid-containing compounds with carbon numbers >4 using Fenton chemistry.
Additionally, SNL has infrastructure and experts to isolate, purify, as well as characterize lignin degrading enzymes. |

Research Focus
Nancy has over 30 years of experience working with a wide variety of fermentation processes and microorganisms to produce specialty chemicals and fuels. She specializes in using biomass sugars in the processes and scaling fermentations from bench to pilot. Nancy is currently involved with two BETO funded scale-up projects to demonstrate lignocellulosic ethanol to jet fuel and commercial scale production of 2,3-butanediol for low carbon chemicals. Nancy has several projects in the area of power-to-gas to develop biomethanation technology for long-term renewable energy storage and recycling carbon dioxide. One is a BETO-funded scale-up project to bring a pilot-scale biomethanation system to a dairy digester in Maine to produce renewable natural gas from waste carbon dioxide and renewable hydrogen. Nancy was also involved in the first BETO funded validation activities to assess project performance funded under BETO’s Funding Opportunity Announcements (FOAs). Validation of FOAs have become a standard practice for BETO.
Prior to NREL, Nancy worked at Zeagen (formerly Coors Biotech, Inc.) developing fermentation processes to produce specialty chemicals for animal feed; specifically, riboflavin production from yeast, xanthophyll from heterotrophic algae, astaxanthin from yeast, and beta-carotene from fungi. The riboflavin process was at commercial scale and her work focused on down scaling oxygen mass transfer and nutrient optimization. Nancy also spent two years at Colorado State University working in their Bioprocessing Center where she focused on developing mammalian and insect cell culture processes at pilot scale for small start-up companies and university research projects.
Nancy conducts her research in NREL’s bench-scale fermentation laboratory which includes thirty-six 500 mL bench scale fermentors and has access NREL's fermentation pilot plant (100L, 1000L, and 9000L vessels). She is also developing online near-infra red analysis for fermentation process control. Nancy also works at NREL’s Energy Systems and Integration Facility where the 20L mobile pressurized gas bioreactor with water electrolysis and the 700L pressurized gas fermentor with 1MW-scale water electrolysis is located. |

| | Our pilot-scale systems are capable of testing multiple biomass-to-fuels and chemical pathways including gasification, fast pyrolysis, catalytic fast pyrolysis, and vapor phase upgrading. Our systems are flexible, allowing for modifications based on new technologies and research areas.
Davison Circulating Riser
The Vapor Phase Upgrading Lab houses two reactor systems: a fluidized bed reactor for the fast pyrolysis (500°C, 20–45 psig, 1–2 seconds residence time) of biomass and a Davison circulating riser (DCR) for performing vapor phase upgrading reactions of pyrolysis vapors. The scale of operations on the pyrolyzer is nominally 2 kg/hour, with nitrogen employed for fluidization (0.5 biomass:N2). Pyrolysis vapor feed rates up to 1 kg/hour (including nitrogen) to the DCR are typically employed to provide short residence times (~1 second) in the DCR. The DCR (500°C–650°C, 20–45 psig, 1–10 seconds residence time) circulates a 2 kg charge of catalyst through a steam stripper and a regenerator (for coke removal) that allows up to 10 to 12 hours of continuous operation per day. Weight hourly space velocity between 10 (typical for pyrolysis vapors) and >100 (vacuum gas oil) enable a wide range of experimental conditions for catalyst evaluation. The lab also houses a Xytel attrition testing unit (to determine if novel catalysts are suitable for circulation in the DCR), fixed gas detection, and an overhead crane.

Thermal and Catalytic Process Development Unit
The Thermal and Catalytic Process Development Unit (TCPDU) is used to test biomass pyrolysis technologies at the pilot scale. The TCPDU can be configured for fast pyrolysis and catalytic pyrolysis. An entrained flow reactor is used to generate the pyrolysis vapors, cyclones to collect char and ash, and a spray condensation train to collect the final products. A recirculating regenerating reactor can be used to catalytically upgrade the pyrolysis vapors. Online analytical capabilities include molecular beam mass spectrometry, gas chromatography, thermal conductivity detection, and nondispersive infrared. Partners can use the TCPDU to test catalysts or bring in their own unit operations to attach to the TCPDU to test their pyrolysis technologies.
The TCPDU is also used to test biomass gasification technologies at the pilot scale. In the gasification configuration, the TCPDU is comprised of a fluid bed reactor for initial volatilization of biomass, a thermal cracker to complete gasification, cyclones for char and ash collection, and a gas scrubbing system. Three different reforming reactors are available and can be used independently or in parallel: fluid bed, packed bed, and recirculating regenerating reactor. Online analytical capabilities include molecular beam mass spectrometry, gas chromatography, thermal conductivity detection, and nondispersive infrared. Partners can use the TCPDU to test catalysts or bring in their own skid to attach to the TCPDU to test syngas upgrading technologies.

The PBC Platform has an array of molecular biology capabilities for microbial metabolic engineering, phenotypic and morphological analysis of bacteria, yeast, fungi, and algae, and analysis of cell growth rates and productivity. Analytical equipment in the laboratories includes more than two dozen HPLC for analyzing soluble metabolites. An array of gas chromatographs (GC) with mass spectrometer (MS) detectors are used to characterize volatile analytes and in-line micro-GC capabilities allow for direct analysis of gas consumption and evolution in bioreactors. An array of fermentation capabilities is available, including 0.2-20L bench-scale reactors suitable for both liquid and gaseous substrate fermentation. The Platform also has ready access to pilot-scale facilities for feedstock processing and pretreatment, high solids saccharification, centrifugation, and filtration. Two complete 1-metric ton/day pilot-scale trains are installed to allow for acidic, alkaline, and steam pretreatments and feed directly to a train of four 9,000-liter fermenters with pre-seed and seed fermentation tanks. All fermenters are equipped for control of pH, DO, temperature, foam control, acid and base addition, agitation control, air/inert gas sparge and overlays, and continuous GC-MS head space analysis for both anaerobic and aerobic operation.
The PBC Platform is actively investigating terrestrial and gaseous feedstock characterization, processing, and bioconversion to diverse fuel and chemical intermediates. This includes microbial strain development, C1 gas (electro)bioconversion (e.g., syngas and carbon dioxide fermentation) and production of fuels, biopolymer intermediates, and performance advantaged bioproducts. Downstream product separations and chemical catalytic upgrading is also of interest. |

This cutting-edge approach is capable of using CO2 as a feedstock, which helps to sequester additional CO2 into the final NIPU products. The CO2 used can be sourced from flue gas, syngas, or fermentative offgas.
We have established a strong understanding of the relationship between NIPU structure and performance. Our team has also successfully patented NIPU polymers that demonstrate comparable performance to conventional incumbents. Our patent portfolio covers novel production methods for monomers, polymers, and associated processing techniques. Our NIPU invention was awarded R&D 100 as a market disruptor in 2020. We are now seeking partnerships with industrial players across various market sectors to advance the technology for commercialization.

| Topic 2: Strategic opportunities for decarbonization of the chemicals industry through biocatalysts | For the development of biocatalysts relevant to lignin valorization, NREL has pioneered the concept of “biological funneling”, wherein an aromatic-catabolic microbe is able to convert a mixture of bio-available aromatic compounds into a single, target product (1-3). We primarily use Pseudomonas putida KT2440 as a biocatalyst. In terms of metabolic engineering, we have worked to “expand the funnel” of aromatic compounds that are bio-available (4), to overcome bottlenecks (5), and to improve the toxicity tolerance of P. putida to substrates, intermediates, products, and supplementary carbon sources using tools such as randomly barcoded transposon insertion sequencing (RB-TnSeq). In parallel, we have developed multiple bioprocess innovations that have been able to achieve the highest titers and rates accessible from lignin-derived aromatic compounds presented to date, up to 24 g/L and 0.66 g/L/hr of muconic acid (6).
In parallel, NREL researchers have developed strategies for the oxidative depolymerization of lignin to cleave recalcitrant carbon–carbon bonds, which has enabled a much higher yield of bio-available aromatic compounds, which has been enabled through autoxidation catalysis (7,8). We have developed counter-current chromatography methods (9) and membrane-based methods (10) to separate oligomers of lignin (which are not typically readily bio-available) from aromatic monomers.
Related to lignin analytics, which is a major challenge in biorefining, NREL has a comprehensive analytical characterization facility to characterize lignin in polymeric, oligomeric, and monomeric forms through NMR spectroscopy, LC/MS-MS, GC/FID-MS, and other methods. We can also provide bespoke model compound syntheses to study isolated compounds.
Lastly, NREL has core capabilities in techno-economic analysis and life cycle assessment that are critical for lignin valorization studies (11 ,12).

Operating pressures range from near ambient for downdraft gasification to 1000 psig for a small integrated fluid-bed system, 150 psig for larger pilot-scale fluid-bed gasifiers, and 300 psig for entrained-flow gasification. Relevant gas cleanup capabilities include bench-scale hot-gas candle filters for particulate removal, warm- and cold-gas cleanup trains, fixed-bed reactor/sorbent contactors, a gas-sweetening absorption system (GSAS), fixed- and circulating-bed sulfur reactor gas cleanup, water–gas shift (WGS) catalyst test vessels (including sour, high-temperature, and low-temperature), regenerable sulfur sorbents, nonregenerable guard-bed sorbents, trace metal sorbents, and tar-cracking catalysts. Previously tested biomass feedstocks include wood, corn stover, switchgrass, municipal solid waste (MSW), railroad ties, construction and demolition debris, turkey litter, algae, and aquatic plants. Custom versatile feeding equipment has been developed for reliably feeding various low-density, fibrous biomass feedstocks to these pressurized gasification systems. Dr. Michael Swanson has participated in over 100 gasification/syngas cleanup projects over 31 years, including nine projects feeding or cofeeding biomass to gasifiers. |

Feedstocks
| Topic 1 and Topic 2 | The Iowa Corn Promotion Board (ICPB) promotes corn and corn-based products on behalf of the corn farmers of Iowa. We develop proprietary chemical processes, in-license university research for further development, make equity investments, and fund fundamental research.
We utilize internal and external expertise through our network of staff and consultants to provide technical input, market development, and project management support to a wide range within the bioeconomy value chain. This expertise was most recently demonstrated by our development and sale of a novel, 1-step process to make Monoethylene glycol directly from glucose.
We are funded by the corn checkoff in Iowa, which we use to invest in:
• Biochemical process development; enzymatic and thermochemical
• Biofuels process development
• Internal and external chemical collaborations
• Expansion of exports of corn and corn products
• Communication of the role of farmers in the sustainable economy
• Sustainable farming practices
• Genetic trait development
We want to collaborate with people focused on corn or corn products as their biochemical feedstock. We offer our above experience with the added connection to the US farmer and the corn processing industry. We expect farmers to grow 5 Billion more pounds of glucose than last year. We have feedstocks; we’re looking for conversion technologies! |
