متن کاملReaction Engineering of Direct Coal Liquefaction
Direct coal liquefaction has been studied and practiced since the 1930s. It was used in Germany during World War II to produce synthetic fuels when there was no oil allowed into the country. Since then, it has been studied in the United States and many different technologies have been investigated. Since the US is rich in coal resources, this is one way to be energy independent. Most of the dev...
متن کاملCatalysis in Direct Coal Liquefaction : Status and Directions for Research
The production of distillate fuels and chemicals from coal has never been economical in a free market economy. The principal factors which contribute to the high cost of coal-derived liquids are the large amounts of hydrogen which must be added to remove heteroatoms and to convert material containing about 5 wt% hydrogen to products with between 12 to 14 wt% hydrogen, the severe reaction condit...
متن کاملBioleaching of Molybdenum from a Coal Liquefaction Catalyst Residue
bioleaching, molybdenum disulfide, catalyst residue Molybdenum disulfide, MoSz, is used as a catalyst in coal-oil coprocessing. For most processes using molybdenum catalysts to be economical, the molybdenum must be recovered and recycled. Chemical recovery schemes have been devised, but typically recover only a fraction of the molybdenum. There are reports in the literature that bacteria can ox...
