Abstract
The present invention relates to a process for producing ethene by the vapor phase dehydration of ethanol using a supported heteropolyacid catalyst. In particular, the present invention involves the use of a supported heteropolyacid catalyst, wherein the supported heteropolyacid catalyst is: i) a mixed oxide support comprising silica and a transition metal oxide, wherein silica is present in an amount of at least 50 wt. %, based on the weight of the mixed oxide support; or ii) a mixed oxide support comprising zirconia and a different transition metal oxide, wherein zirconia is present in an amount of at least 50 wt. %, based on the weight of the mixed oxide support. When used in a process for the preparation of ethene by vapor phase dehydration, and after attaining steady-state performance of the catalyst, the process may be operated continuously with the same supported heteropolyacid catalyst for at least 150 hours without any regeneration of the catalyst.
