1. A process for ethanol dehydration comprising:
splitting an ethanol feed stream into a first charge stream and a second charge stream;
adding an amount of steam to said first charge stream, wherein a steam to ethanol ratio is between 1.0 to 2.0 wt/wt; and
reacting said first charge stream and said second charge stream at reaction conditions in the presence of a catalyst to produce an ethylene effluent stream.
