Abstract
The present invention relates to a process for the production of light weight olefins comprising olefins having from 2 to 3 carbon atoms per molecule from an oxygenate feedstock. The process comprises passing the oxygenate feedstock to an oxygenate conversion zone containing a metal alumino phosphate catalyst to produce a light weight olefin stream. A propylene stream and/or mixed butylene is fractionated from said light weight olefin stream and a medium weight Cto Cstream is cracked in a separate olefin cracking reactor to enhance the yield of ethylene and propylene products.
