Abstract
A C4+ naphtha hydrocarbon feed is converted to light olefins and aromatics, by contacting the feed with a catalyst containing ZSM-5 and/or ZSM-11, a substantially inert matrix material such as silica and/or clay, having less than about 20 wt % active matrix material based on total catalyst composition, and phosphorus.
