The activity of commercial catalyst which contained 50% of ZSM-5 zeolite (in nickel form) and silica was compared with the activities of zeolite (50% of Ni, H-ZSM-5) laboratory catalysts which included aluminium oxide and nickel oxide (8 wt.%). Determinations were carried out with n-hexane (T=275 to 400 C, H2 : CH=7 : LHSV=1h-1) and a mixture of paraffin hydrocarbons (p=5.0 and 7.0 MPa, H2:CH=500 Nm3/m3, LHSV=2h-1). The experimental result show that the commercial dewaxing catalyst displayed lower hydrocracking activity than laboratory catalysts. Determinations of catalytic activity using hydrotreated light diesel oil (p=3.5 MPa, LHSV=3h-1, H2:CH=500 Nm3/m3) have revealed that the activity of the catalyst obtained on the aluminium oxide can be modified by decreasing ion exchange level in the zeolite. Hydrocracking activity of catalyst was found to decrease considerably when zeolite content was reduced from 50 to 30 wt.%.
