Phenanthrene was hydrocracked in a batch stirred tank reactor over catalysts containing WS/sub 2/ and H-mordenites of different silica/alumina ratios in the temperature range 400 to 500/sup 0/C at a constant pressure of 1800 psi. Hydrocracking of phenanthrene was found to be a first order reaction with respect to phenanthrene concentration with an Arrhenius activation energy of 20.8 Kcal/mole. An increase in the silica/alumina ratio of H-mordenite from 10 to 50 increased the hydrocracking rate constant three times. Phenanthrene was found least reactive and the first order rate constants varied in the order phenanthrene less than naphthalene less than anthracene. Phenanthrene hydrocracking was found to proceed through a multistep mechanism of hydrogenation, isomerization, and cracking occurring in that order.
