In order to improve the economy of the conversion process of polyaromatic molecules to their hydroaromatics analogs, catalytic hydrogenation of phenanthrene has been carried out under pressure of different simulated coke-oven gases instead of pure hydrogen. The influence of reaction time, temperature and pressure on the hydrogenation yields and on the nature of the obtained products has been studied. Comparisons have been made with reaction with pure hydrogen in the same conditions. The influence of the different components of a real coke-oven gas has also been pointed out. The results indicate that coke-oven gas can be used if the goal is not to obtain perhydroaromatics compounds for a thermal cracking, but to give partly hydrogenated compounds to be used as hydrogen donor solvent in a coal liquefaction process. The results have been applied to coal-tar highly aromatic fractions.
