Summary 1. An aromatized extract, suitable for the production of phenanthrene and certain other individual hydrocarbons by high-temperature hydrogenation, is obtained by extraction of low-sulfur gas oil from catalytic cracking, with a b.p. up to 500°C, with wet pyridine. 2. As a result of study of the hydrogenation of an extract with b.p. 300–450°C over aluminum-cobalt-molybdenum oxide catalyst and without catalyst, at a pressure from 20 to 60 atm and a temperature of 600–700°C in the presence of water vapor, it has been shown that under optimum conditions up to 25% phenanthrene may be obtained, plus naphthalene and other valuable hydrocarbons. In connection with the fact that the content of phenanthrene attains 65% in broad fractions, and anthracene is practically absent in them, 95% phenanthrene can be isolated from the hydrogenation product by relatively simple methods-pressing, etc.
