ABSTRACT:
The present invention relates to a process for the production of light olefins comprising olefins having from 2 to 4 carbon atoms per molecule from a crude oxygenate feedstock. The crude oxygenate feedstock comprises an alcohol, and water. The process comprises passing the crude oxygenate feedstock to catalyst to a distillation with reaction zone to convert the alcohol to an ether and produce an ether product having a reduced water relative to the crude oxygenate feedstock and a first water stream. The ether product is passed to an oxygenate conversion zone containing a metal aluminosilicate catalyst to produce a light olefin stream. The use of crude oxygenate feedstock, having a high proportion of water, combined with a process for producing additional water in the conversion of the alcohol to an ether, actually reduces the amount of water contacted with the water sensitive, metal alumino-silicate catalyst in the oxygenate conversion zone which provides the advantage of extended catalyst life and greater catalyst stability in the oxygenate conversion zone.
