7.超強酸で低分子化した瀝青炭の水素化と熱分解反応性

抄録

Illinois #6 coal was treated using trifluoromethanesulfonic acid (TFMS) in the presence of isopentane and methylcyclopentane at 120℃ for 3h. Thus the extraction yield in THE was increased to 80-90%. The THF solubilized coal was then hydrogenated over a Ru/activated carbon catalyst at 120℃ for 48h under a hydrogen pressure of 10MPa. The liquid product was obtained after the solvent removal, and the H/C atomic ratio increased from 0.88 to 1.52 by the reaction. The increase in pyrolysis reactivity of the hydrogenated liquid was due to hydrogenation of aromatic rings.
