石炭化度の影響

Liquefaction of four ranks of coals, Mowell coal (C: 66.1%), Taiheiyo coal (C: 76.3%), Miike coal (C: 82.6%) and Smokey-River coal (C: 89.9%) with ethylene were studied using petroleum vacuum residue as a solvent. A mixture of one part of coal and two parts of Khafji vacuum residue was heat-treated at 420°C for 60 min. with 8.00 1/ (100g sample) of ethylene.
Results obtained from the amounts of benzene insoluble matter (BI) and quinoline insoluble matter (QI) in the reaction mixture, and gas analysis were summerized as follows:
(1) Ethylene was effective for the liquefaction of coals used for this study except Smokey-River coal.
(2) The decrease of QI with ethylene was greater than that of BI. Therefore, ethylene was effective for the formation of preasphaltene.
