CATALYST FOR CATALYTIC CRACKING OF HYDROCARBON, USED IN OBTAINING LIGHT OLEFIN, AND METHOD OF OBTAINING THEREOF

摘要

FIELD: chemistry.SUBSTANCE: invention relates to catalytic cracking of hydrocarbons. Described is method of obtaining light olefins by catalytic cracking of hydrocarbons with 4 or more than 4 carbon atoms, with boiling point 30-200°C, in presence of catalyst, characterised by the fact that 0.01-5.0 wt % of MnOand 1-15 wt % of POare simultaneously added to catalyst components, where catalyst components contain 1-50 wt % of zeolite, 21-70 wt % of clay and 1-40 wt % of inorganic oxide and where both MnOand POare introduced into (modify) each of catalyst components, such as ZSM-5 zeolite, clay and inorganic oxide.EFFECT: increase of product outcome.10 cl, 1 dwg, 6 tbl, 9 ex
