Biological production of ethanol from coal. Final report ...
1992-12-1 Synthesis gas, a mixture of CO, H{sub 2}, CO{sub 2}, CH{sub 4} and sulfur gases, is first produced using traditional gasification techniques. The CO, CO{sub 2} and H{sub 2} are then converted to ethanol using a bacterial culture of Clostridium 1jungdahlii. Ethanol is the desired product if the resultant product stream is to be used as a liquid fuel.

Biological production of ethanol from coal. [Quarterly report], December 22, 1990--March 21, 1991. Previously studies have shown the importance of both medium composition and concentration and medium pH on ethanol production of Clostridium ljungdahlii in fermenting CO, CO {sub 2} and H {sub 2} in synthesis gas.

Biological production of ethanol from coal synthesis gas ...
1993-9-1 The anaerobic bacteriaClostridium ljungdahlii produces ethanol and acetate from CO, CO 2, and H 2 in synthesis gas. Early studies with the bacterium showed that relatively high concentrations of ethanol could be produced by lowering the fermentation pH and eliminating yeast extract from the medium in favor of a defined medium.

China creates world's first coal-to-ethanol production ...
2017-3-19 Using ethanol can reduce oil dependence and greenhouse gas emissions. But previously, ethanol could only be made from plant materials, such as corn, sugar cane, or grasses. Accomplished industrial production of ethanol from coal-based syngas will greatly ease the pressure of demand for ethanol fuel in China, given its abundant coal resources.

Ethanol from Coal, Natural Gas, and Coke; not from Corn ...
2010-11-15 Each one will produce approximately 400,000 tons of ethanol per year. Combined, the two facilities could provide more than 25 percent of China’s current ethanol demand of 3 million tons per year. This demand, moreover, is expected to grow 10 percent per year. The feedstock for the Chinese plants will be coal, which has a two-pronged benefit.

2018-2-1 Fig. 1 shows a flow diagram for the proposed process for converting a domestic biowaste–coal mixture to synthetic ethanol, via gasification and alcohol synthesis. The synthetic ethanol production process introduced and analyzed by the National Renewable Energy Research Institute and Gwak et al. was modified and used for this study. Similar to previous studies, the proposed synthetic ethanol production
