  • Study on Direct Liquefaction Character of Huainan Gas Coal

    WANG Jin-rong,YUAN Liang,ZHANG Bing-guang,CAO Zhi-chuan(Huainan Mining Group, Huainan 232001,China)

    The huainan coal-mining district possesses a good transport service, a well-situated, abundant power and water supply, pleasant weather. The gas coal resource is abundant and its direct liquefaction character is also good in Huainan coal mining district. Its C, H, and O elemental content and Qgr,dmmf and Qnet,ar heating value are more and more closed with the natural petroleum comparison with the long flame and brown coal Therefore it may consider that the comprehensive economic benefit of Huainan gas coal direct liquefaction will be better than the low degree of coalification coal such as non-coking coal, long flame coal and brown coal.

    Coal based activated carbon was made by different production process and Taixi anthracite as raw material. The pore structure of this coal-based activated carbon is analysis by N 2 adsorption method on CARLO-ERBA 1800 automatic apparatus. The N 2 isothermal adsorption data are treated by BET equation to obtain BET surface area and pore volume of activated carbon and to calculate the average pore radius. The pore diameter distribution of activated carbon is studied. Adsorption and desorption property of activated carbon were analyzed and evaluated by BWC. The result is shown that, the best adsorption and desorption property of activated carbon is made by catalytic activation process.
