Abstract

Hydrogen transfer from naphthenes to aromatics, coal, resid, and coal plus resid has been investigated at 430 °C in a N 2 atmosphere. The reaction of perhydropyrene (PHP) with anthracene (ANT) resulted in the formation of pyrene (PYR) and dihydroanthracene. The weight percents of the products formed varied according to the ratio of ANT:PHP used with a minimum appearing at a 2:1 weight ratio. Longer reaction times and high ANT:PHP ratios also yielded tetrahydroanthracene. Reactions of Illinois No. 6 coal from the Argonne Premium Coal Sample Bank with PHP, ANT, and PYR resulted in higher coal conversion with PHP and lower with ANT and PYR. Reactions of PHP with resid resulted in less retrogressive reactions occurring in the resid than with either PYR or ANT
