A hybrid catalyst, which was prepared by physical mixing of a H-ZSM-5 and Pd/SiO{sub 2}, showed an excellent activity for the hydrocracking of n-paraffins at low reaction temperature (503 K). In the n-heptane cracking, the hybrid catalyst gave only isomerized heptane and propane and equimolar amount of i-butane whereas the products on H-ZSM-5 alone distributed from C{sub 3} to C{sub 9} and C{sub 4} products contained all kind of paraffins and olefins. The wide product distribution for H-ZSM-5 system should be attributed to the reaction path comprising oligomerization and cracking of the oligomer. The simple products for the H{sub 2}-hybrid system should be formed through no other reaction path than the primary cracking reaction on H-ZSM-5. 7 refs., 7 figs.
