Production of Advanced Biofuels

Statement of the Problem: The development of lignin derived energy products is one way to increase the value of bio-refinery residues. Gasification of (lignin-rich) Biorefineries residues, followed by product gas cleaning and anaerobic fermentation, offers a potential to produce higher added-value products such as biofuels and chemicals. MILENA indirect gasification allows complete fuel conversion and produces a high value gas composed of CO, H₂ and CO₂, as well as compounds such as CH₄, C₂-C₄ gases, benzene, toluene and xylene (BTX), and tars. The separation of the most valuable components of the product gas is a good way to maximize the value from the feedstock via co-production schemes. The product gas, after appropriate cleaning to remove impurities, can be applied in the gas fermentation process. Some anaerobic microorganisms can be used as a biocatalyst for the microbial conversion of syngas into short-chain organic acids and alcohols (i.e. acetate and ethanol). The ability of these microorganisms to withstand some of the impurities contained in the syngas and their flexibility to use different syngas compositions makes them an attractive alternative to the chemical catalytic processes.
