ZEOLITE-CONTAINING CATALYST, METHOD FOR PRODUCTION AND TRANSITION METHOD OF MIXTURE OF LOW MOLECULAR PARAFFIN AND OLEFIN HYDROCARBONS IN THE CONCENTRATE OF AROMATIC HYDROCARBONS OR HIGH-OCTANE NUMBER COMPONENT OF BENZINE (VARIANTS)

摘要

FIELD: chemistry.;SUBSTANCE: zeolite-containing catalyst is proposed for conversion of a mixture of low-molecular paraffin and olefin hydrocarbons into a concentrate of aromatic hydrocarbon or a high-octane number component of benzine, containing zeolite ZSM-5 with silicate module SiO₂/Al₂O₃ = 30–100 mol/mol and a residual content of sodium oxide 0.03–0.07 wt. %, elements of zeolite structure and a binder, and as elements of zeolite structure, the catalyst contains zirconium oxide, scandium oxide, cerium oxide, tin oxide, zinc oxide, lead oxide, or a mixture of oxides of these metals. Invention also discloses methods for production of a zeolite-containing catalyst.;EFFECT: technical result is achievement of a high phase frequency of the zeolite and improvement of quality and yield of target products on claimed catalyst.;4 cl, 11 ex, 3 tbl
