Catalysis in Direct Coal Liquefaction : Status and Directions for Research
نویسنده
چکیده
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 conditions (temperature and pressure) and the relatively low rates of conversion which are experienced.

Effect of Recycle Solvent Hydrotreatment on Oil Yield of Direct Coal Liquefaction
Effects of the recycle solvent hydrotreatment on oil yield of direct coal liquefaction were carried out in the 0.18 t/day direct coal liquefaction bench support unit of National Engineering Laboratory for Direct Coal Liquefaction (China). Results showed that the hydrogen-donating ability of the hydrogenated recycle solvent improved and the hydrogen consumption of solvent hydrotreatment was incr...
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...

Pulverized Wyoming subbituminous coal was beneficiated by low-pH oil agglomerationat CONSOL to prepare the coal for direct liquefaction. Conventional cleaning is not veryeffective in cleaning this coal; for example, conventional oil agglomeration only givesabout 20% ash rejection. To improve ash rejection, the coal-water slurry was acidifiedto a pH of about 0.5. Oil agglomeratio...

متن کاملDirect Coal Liquefaction with Fe3O4 Nanocatalysts Prepared by a Simple Solid-State Method
Fe3O4 nanoparticles were prepared by a simple solid-state method under ambient conditions. The obtained nanoparticles, with small size and large surface area, were used as a catalyst for direct coal liquefaction (DCL). The results display that high conversion and oil yield were achieved with the nanocatalysts in direct liquefaction of two kinds of coals, i.e., Heishan coal and Dahuangshan coal....
