ABSTRACT:
A process for rejuvenating crystalline aluminosilicayte zeolite-containing catalysts which have become at least partially deactivated through use in a hydrocracking process. Used, deactivated catalysts are treated with ion-containing solutions, particularly those containing hydrogen ions and hydrogen precursors, at a pH of from 3.5 to about 9, such that the alkali metal content of the catalyst is substantially reduced to thereby rejuvenate the catalyst to at least its original fresh activity in a hydrocracking process.
