Zusammenfassung:	FIELD: chemistry.SUBSTANCE: invention relates to a catalyst composition for hydrocarbon conversion. Catalyst contains in terms of total weight of catalyst in wt%: 25-30 zeolite Y, 15-20 zeolite ZSM-5, 50-60 beta zeolite. Described also is a method of producing propylene, involving cracking hydrocarbon raw material.EFFECT: higher yield of propylene during cracking with fluidised catalyst.14 cl, 1 tbl, 2 ex Изобретение относится к каталитической композиции углеводородного превращения. Катализатор содержит в пересчете на общий вес катализатора в вес.%: 25-30 цеолита Y, 15-20цеолита ZSM-5, 50-60 бета цеолита. Описан также способ получения пропилена, включающий крекинг углеводородного сырья. Технический результат - увеличение выхода пропилена в процессе крекинга с псевдоожиженным катализатором. 4 н. и 10 з.п. ф-лы, 1 табл., 2 пр.
