CATALYST FOR REFORMING GASOLINE FRACTIONS AND METHOD FOR PRODUCTION THEREOF Russian patent published in 2022 - IPC B01J23/42 C10G35/04 B01J23/62 B01J27/06 B01J32/00 B01J35/08 B01J37/08 C10G35/85 

FIELD: chemistry.

SUBSTANCE: invention relates to production of a catalyst for reforming gasoline fractions in a moving bed with its continuous regeneration, based on a spherical alumina carrier prepared by hydrocarbon-ammonia molding, which contains platinum, tin and chlorine. Described catalyst for reforming gasoline fractions contains, wt.%: platinum 0.1–0.3, tin 0.1–0.4, chlorine 1.0–1.1 and an alumina support from a mixture of aluminum hydroxide powders containing aluminum hydroxide in form of 60 wt.% high-porosity boehmite, having a pore volume of 0.9–1.1 cm³/g, and 40 wt.% low-porosity pseudoboehmite, having a pore volume of 0.5 cm³/g — the rest, and also the method of its production is described.

EFFECT: high mechanical strength of the catalyst with minimum losses during attrition, which ensures high activity, selectivity and stability of the catalyst at high rigidity of the process.
