Abstract

Process for producing alkene(s) from an oxygenate feedstock in a reactor by dehydration in the presence of a supported heteropolyacid catalyst. The pore volume of the supported heteropolyacid catalyst satisfies the following formula:PV>0.6−0.3[HPAloading/Surface Area of Dried Catalyst]where;
