摘要：

Recent research has resulted in a number of promising biological pathways to produce clean fuels from coal. These processes all involve two or more steps: either the biosolubilization of coal, followed by bioconversion to ethanol or methane; or conversion of coal to synthesis gas, followed by bioconversion into alcohols or methane. Sulfur may also be removed from the solubilized coal or synthesis gas in a separate, or concurrent, biological step. This paper presents research results from both the direct and indirect conversion of coal to liquid fuels using biological processes. A review of direct conversion techniques in producing liquid-fuels from coal in a serial conversion process is presented. In addition, bioreactor design data for the conversion of CO, CO2 and H-2 in synthesis gas by Clostridium ljungdahlii in both batch and continuous culture are reviewed and discussed.
