METHOD OF CATALYST PREPARING FOR AROMATIZATION OF C-C-HYDROCARBONS Russian patent published in 1995 - IPC

Abstract SU 1676140 A1

FIELD: catalytic chemistry. SUBSTANCE: zinc and/or gallium is applied on high-silicon zeolite type ZSM-5 with silicate modulus 39-280 in ammonium or hydrogen form or by impregnation or by ion exchange following by drying and calcination at 620-800 C. Under these conditions catalyst prepared shows improved activity as compared with known one. Conversion and selectivity reach values 41.8% and 68.4% as compared with 35% and 51%, respectively. EFFECT: enhanced activity and selectivity of catalyst. 1 tbl
