| description | FIELD: catalyst preparation methods. ^ SUBSTANCE: modified zeolite-containing catalyst preparation comprising heat treatment of initial catalyst in air flow and ion exchange is characterized by that initial catalyst utilized is zeolite Zeokar 10 used in petroleum processing for cracking of petroleum fractions, which catalyst is heated in flow-type reactor with air flow to 500-550°C for 6-12 h, after which treated for 4-6 h with 0.5-0.15 N hydrochloric acid solution, rinsed with water, heated once again for 6-12 h in air flow to 500-550°C, treated for 4-6 h with 0.5-0.15 N aqueous magnesium acetate solution, rinsed with water, and finally heated for 5-12 in air flow to 500-550°C. ^ EFFECT: increased catalytic activity and productivity in liquid phase at reduced temperatures (140-250°C) and pressures (1 to 30 atm), and enabled use of catalyst in continuous condensation and alkylation processes. ^ 9 ex |
