METHOD OF PREPARING CATALYST FOR OLIGOMERIZATION OF LOWER OLEFINS

摘要

FIELD: catalysts for petrochemical processes. SUBSTANCE: invention consists in thermocatalytic pyrolysis of associated or natural gas at temperature 310 to 960 C, volumetric raw material supply rate 800-1200 h-1 during 0.3-10 h in presence of nickel chloride followed by recovering fraction 45-400 mcm by means of screening resulting catalytic paste on molecular sieves. EFFECT: eliminated use of diethylaluminum chloride in preparation of catalyst. 3 tbl, 6 ex
