FIELD: oil-and-gas industry.
SUBSTANCE: invention covers a new olefins cracking catalyst. This catalyst comprises zeolite characterised by the silicon dioxide-to-aluminium oxide ratio of 400 or more and subjected to ion exchange for the decreasing of the content of alkaline and alkaline-earth metals to below 100 ppm and, then subjected to flushing by steam and acid.
EFFECT: catalyst is characterised by better selectivity relative to the propylene yield, decreased amount of aromatic compounds and methane.
