Abstract: Zeolite-based hydrocracking catalysts having a low residual sodium content achieved by ammonium cation exchange are loaded with a hydrogenation agent comprising a mixture of a Group VIII non-noble metal and a Group VI-B metal by a process which avoids to a high degree loss of effective catalytic surface area. The use of an ammonium ion exchange medium having a pH value within critical limits for the second of two necessary cation exchange procedures is an essential feature of the process.
