Hydrocracking of Vacuum Gas Oil on Bimetallic Ni-Mo Sulfide Catalysts Based on Mesoporous Aluminosilicate Al-HMS

Abstract

The activity and selectivity of a bimetallic Ni-Mo sulfide catalyst based on mesoporous aluminosilicate Al-HMS with Si/Al ratio of 10 in the vacuum gas oil hydrocracking process in a reactor with a fixed catalyst bed was studied. The dependence of the activity and selectivity of the NiS-MoS₂/Al-HMS (Si/Al = 10) catalyst on the process parameters (temperature, hydrogen pressure, volume stock feed rate, etc.) was investigated. It was shown that in the 380-450°C range at 5 MPa hydrogen pressure the catalyst ensures conversion of the heavy part of the hydrocarbon stock into fuel fractions with high selectivity in the middle distillates and makes it possible to reduce the sulfur content of the liquid hydrocracking products.
