The present invention provides a process for the preparation of ethene by vapor phase chemical dehydration of a feed comprising ethanol, said process comprising contacting the feed with a supported heteropolyacid catalyst in a reactor, wherein the feed temperature is at least 250&#xb0; C. and the pressure inside the reactor is at least 0.80 MPa but less than 1.80 MPa.

Process for preparing ethene

A process for the acid-catalyzed dehydration of ethanol, the process comprising the steps of distilling an ethanol feedstock () comprising at least one nitrogen-containing contaminant to form an overhead stream () and a bottom stream comprising ethanol (), wherein the distillation has a reflux ratio of at least 20:1; and reacting the bottom stream in the presence of an acid catalyst to form a product stream comprising ethylene.
