Production of Diesel and Jet Fuel Intermediates Using Hy brid Gasification-Syngas Fermentation

The hybrid conversion process has feedstock flexibility and utilizes all components of biomass including lignin to syngas. Syngas fermentation operates near ambient pressure and temperature. Biological production of higher alcohol biofuels, such as n-butanol and n-hexanol, from syngas components (i.e., CO, CO2 and H2) is a promising approach for the commercialization of renewable, carbon-neutral liquid transportation fuels. n-butanol and n-hexanol have higher energy densities than ethanol and are compatible with current fuel infrastructure Butanol and hexanol are considered intermediates for the production of diesel and jet fuels. An analysis of 16S rRNA genes of continuous fermentation culture revealed that the bioreactor contained a mixed culture consisting of 56% strain CP15 and 34% Clostridium propionicum [1]. Findings presented a new opportunity for production of intermediates of jet and diesel fuel from syngas using mixed culture. MATERIALS AND METHODS
