Biological production of fuels from coal-derived gases: Quarterly report, June 20, 1987-September 20, 1987

OSTI ID:5700172

The technical feasibility of converting CO, H/sub 2/ and CO/sub 2/ from synthesis gas to ethanol and acetate has been demonstrated in a continuous stirred-tank reactor with both continuous gas and liquid feed. This report describes the equipment and procedures for continuous operation, as well as steady-state experiments carried out at three steady-state conditions. Although the operating conditions for continuous operation have not been optimized and a significant amount of acetate remains in the product stream, the feasibility of using a bacterial process for synthesis gas conversion to liquid fuels has been demonstrated. Future work during subsequent contracts should concentrate on producing a single liquid fuel as a product, increasing the product concentration, and defining and optimizing reaction conditions for maximizing, product yield. 3 refs., 17 figs.
