CATALYST FOR PRELIMINARY HYDROFINING OF STRAIGHT-RUN GASOLINE FRACTION MIXED WITH GASOLINE OF SECONDARY THERMAL PROCESSES AND METHOD FOR PRODUCTION THEREOF (VERSIONS) Russian patent published in 2016 - IPC B01J23/28 B01J23/755 B01J27/14 B01J21/04 B01J23/30 B01J37/02 B01J37/08 C10G45/08 

FIELD: chemistry.

SUBSTANCE: invention relates to catalysts of preliminary straight-run gasoline fraction mixed with gasoline secondary thermal processes. Catalyst according to the first version contains 6.0-10.0 wt% molybdenum oxide, 3.0-7.0 wt% of nickel oxide, 0.2-0.35 wt% of phosphorus on a support, which is a solid solution of molybdenum oxide in aluminium oxide in molar ratio MoO₃/Al₂O₃ 1:10-1:20 - the rest. Catalyst in the second version contains 3.0-7.0 wt% of nickel oxide 0.2-0.35 wt% of phosphorus on a support, which is a solid solution of tungsten oxide in aluminium oxide in molar ratio WO₃/Al₂O₃ 1:16-1:35 - the rest. Invention also relates to production of each of the catalysts.

EFFECT: disclosed catalysts have high catalytic activity.
