Hydroconversion of n-heptane and toluene has been studied over a commercially proven Ni-W/SiO2-Al2O3 amorphous base hydrocracking catalyst (suitable for maximizing middle distillates production from heavier feedstocks) under a wide range of operating conditions (pressure: 400-1200 psig; temperature: 315-360°C, liquid hourly space velocity (LHSV) ≃ 1 h-1 and molar hydrogen/hydrocarbon feed ratio: 6-8) to assess the hydrogenation and cracking activities of the catalyst screening. Hydroisomerization followed by hydrocracking, ad hydrogenation followed by isomerization have been found to be the major reaction with n-heptane and toluene respectively as the feeds. The hydroconversion of toluene gives a very high selectivity of hydrogenated product. With n-heptane, a very high selectivity of hydroisomerized product, together with a high ratio of hydroisomerized to hydrocracked product, is obtained.
