<p>A process for hydrogenolysis of hydrocarbons in the presence of a fluidized catalyst to thereby obtain light products, which process comprises withdrawing at least part of the fluidized catalyst as used catalyst out of the reaction system, hydrogenating at least part of the used catalyst to solubilize toluene-insoluble carbonaceous materials deposited on the catalyst, and recycling the thus regenerated catalyst to said hydrogenolysis step. According to this process, the used catalyst is regenerated by hydrogenation and in turn recycled to the hydrogenolysis step in a highly active form, and hence coke production is remarkably depressed within the reactor, the coke level of catalyst is controlled at a level not higher than a specified level, and coke stain of the reactor wall is avoided. Further, since this process is based on hydrogenation treatment which is fundamentally different from the conventionally employed oxydizing roasting process, this process involves no such problems in catalyst regeneration as has been encountered with the conventional process.</p> |
