Abstract
Liquid product rich in benzene, toluene and xylene and having a substantially lower mid-boiling point than heavy reformate feedstock or similar feedstock, such as, for example, from pyrolysis gasoline, of a class having an initial boiling point between about 230.degree. F and about 250.degree. F and an end point between about 350.degree. F and about 430.degree. F, and gaseous product rich in light olefins and isoparaffins which is good alkylation plant feed are produced by contacting said heavy reformate feedstock or said similar feedstock with a porous acid-active zeolite catalyst having a fluid activity index of at least about 18 in a fluidized catalyst system absent added hydrogen at a temperature of from about 800.degree. F to about 1200.degree. F, a catalyst/oil (i.e. heavy reformate or similar feedstock) weight ratio of from about 0.5 to about 40 and a catalyst residence time of from about 0.1 second to about 20 seconds.
