In order to clarify the hydrocracking ability of the molten zinc chloride, batch autoclave tests of anthracene and phenanthrene were carried out and an analysis of the products was undertaken using GC-MS, thereby studying the catalytic behavior of ZnCl₂ on the basis of these results. Several parameters affecting the hydrocracking of anthracene such as temperature, hydrogen pressure and duration of reaction were investigated. Over the molten zinc chloride, the reaction of anthracene proceeds through the formation of 9, 10-dihydro, tetrahydro, and octahydroanthracene, followed mainly by isomerization, ring opening and cracking of tetrahydroanthracene to produce naphtalene derivatives. (These hydrogenation and cracking operations were repeated, yielding benzene derivatives). These results were compared with the reported results using bifunctional catalysts. The hydrocracking of phenanthrene over the molten zinc chloride proceeds primarily through 9, 10-dihydro and tetrahydrophenanthrene to give the hydrocracked products and its reaction scheme is also discussed.
