概要

100 samples of recycle solvent were obtained from continuous opera-tion (50 days) of 1 ton/day coal liquefaction plant at Kimitsu. Phenanthrene and anthracene derivatives in the recycle solvents were analyzed in detail by the technique of selective ion measurement GC/MS. According to the replacement of the initial solvent by coal-derived products, the amounts of phenanthrene derivatives decreased remark-ably, while those of anthracene derivatives decreased slightly. For phenanthrene deriv-atives, octahydrophenanthrenes play an important role as hydrogen donors by releasing eight hydrogen atoms in the recycle solvent, on the other hand for anthracene deriva-tives, tetrahydroanthracene plays an important role by releasing four hydrogen atoms. This results indicate that hydrogen donatable ability of phenanthrene derivatives is twice as large as the ability of anthracene derivatives.
