Abstract

This research program consists of (1) the solid catalyst-aided reforming of various petroleum based oils and heavy coal oils into Solvolysis solvents and the secondary hydrogenolysis, (2) a search for pre-treatment for improvement on the sub-bituminous coal liquefaction yield, and (3) a search for measures for improvement on the brown coal liquefaction yield. Studied in this fiscal year are (1) the high-temperature short-contact time liquefaction of brown coal, (2) the role of catalyst support for selective upgrading of SRC (solvent refined coal), and (3) reforming of thermal melting feature of low rank coal by preliminary deashing at room temperature. In relation with Item (1), it is found that the dehydrogenation or reaction to carbonization of molecules involved in hydrogen donation is structure-sensitive but that thermolysis of coal is accelerated under high-temperature conditions to allow transfer hydrogen to contribute uniformly. It is deemed also that matching is excellent between hydrogen transfer and thermolysis, that the solvent dissolution level is elevated, and that the reaction short in duration inhibits consecutive polymerization reaction. These are supposed to be effective in improving on the liquefaction yield and in rendering heavy constituents lighter. In relation with Item (2), it is found that the experimentally manufactured  More>>

In relation with Item (2), it is found that the experimentally manufactured catalysts are effective in reducing the weight of heavy constituents. In relation with Item (3), a carbonization reforming method is experimentally implemented in which the ash that affects carbonization is further removed by a pre-treatment at room temperature.
