Method of producing propylene in the presence of a macroporous catalyst present in the form of spherical balls

摘要

Propylene production by direct conversion of a feed comprising C4 and C5 olefins comprises passing the feed through a reactor containing a catalyst comprising a zeolite and an alumina-based support. The catalyst is in the form of spherical beads with a diameter of 1-3 mm, a macropore volume of 0.1-0.2 ml/g and a mesopore volume of 0.25-0.35 ml/g.
