Abstract
A multi-step process for converting non-aromatic hydrocarbons (preferably a gasoline-type hydrocarbon mixture) to lower olefins (preferably, ethylene and propylene) and aromatic hydrocarbons (preferably benzene, toluene and xylene) comprises, in sequence, a first reaction step, a first separation step, a second reaction step, and a second separation step, wherein the reaction severity of the first reaction step is lower than in the second reaction step so as to maximize olefins and aromatics yields.
