水素化溶媒を用いる石炭のソルボリシス ＶＩ カナダ炭のソルボリシス

Abstract

Solvolysis liquefaction of twelve Canadian coals using hydorogenated anthracene oil has been carried out using 50ml tubing bomb reactor. The coal conversion and the amounts of gaseous products were discussed with H/C atomic ratio and the chemic-al structure of coal determined by 13C solid-state NMR. The toluene soluble matters obtained by solvolysis coal liquefaction were analyzed by 1H-NMR. The results obtained are summarized as follows.1) Yields of pyridine insoluble matters were less than 40 percent in cases of some sub-bituminous coals and less than 30 percent in cases of bituminous coals. The formation of preasphaltene was promoted on the coal with the high H/C atomic ratio.2) The cross-links in coals seemed to disturb the formation of preasphaltene from the analyses of 13C-NMR of coals.3) Yields of toluene insoluble matters ranged from about 60 to 70 percent in cases of sub-bituminous and bituminous coals and did not have a certain regularity such as a rela-tionship with H/C atomic ratio among these coals.4) The analyses of 13C-NMR also showed that methane and CO and CO2 were produced by the decomposition of alkyl chains and by the decarboxylation of carbonyl groups in coals, respectively, at the solvolysis reaction.5) Bituminous coals solved in liquefaction solvent as a toluene soluble matter much more than sub-bituminous coals and lignites.
