A series of catalysts made of Ni, Mo and NiMo sulfide encaged in HY zeolites (Si/Al = 3 to 17) were tested for the hydroconversion of heptane. The reaction was carried out at P(H2) = 8 MPa and with a constant supply of H2S. Propane and isobutane were the main products, but bimolecular cracking processes occurred to some extent. The yield of heptane isomers was low, showing a deficient hydrogenation function. The influence of the Si/Al ratio upon catalytic activity and selectivity was examined.
