Bimetallic Ni—Mo Sulfide Catalysts Based on Mesoporous Aluminosilicate (Al-HMS) in Shale Oil Hydrocracking

Abstract

The activity and selectivity of bimetallic Ni—Mo sulfide catalysts based on mesoporous aluminosilicate (Al-HMS) with a Si/Al ratio of 5 in shale oil hydrocracking were investigated in a fixed-bed catalytic reactor. The temperature dependences of the activity and selectivity of NiS—MoS₂/Al-HMS (Si/Al = 5) were studied. It was shown that this catalyst in the temperature range 330-400°C at an H₂ pressure of 5 MPa converted the shale oil heavy fraction into fuel fractions with high selectivity for the middle distillate and reduced by 78% the sulfur content in the liquid hydrocracking products.
