Title: PROCESS FOR SELECTIVELY PRODUCING LIGHT OLEFINS
Abstract:
The invention is related to a catalyst and a process for selectively producing light (i.e., C2-C4) olefins from a catalytically cracked or thermally cracked naphtha stream. The naphtha stream is contacted with a catalyst containing from about 10 to 50 wt.% of a crystalline zeolite having an average pore diameter less than about 0.7 nanometers at reaction conditions. The catalysts do not require steam activation.
