Abstract
A process for producing ethylene from an ethanol feedstock comprises a step of subjecting the ethanol feedstock to a dehydration reaction in the presence of a supported heteropolyacid salt catalyst. The supported heteropolyacid salt catalyst includes a support and a heteropolyacid salt compound which is carried on the support and which is represented by a formula as defined herein.
Claims10
A process for producing ethylene from an ethanol feedstock, comprising a step of subjecting the ethanol feedstock to a dehydration reaction in the presence of a supported heteropolyacid salt catalyst.
