ABSTRACT:
An activated alumina catalyst containing alkali metal, sulfur, iron and silicon in an amount of 0.05 wt. % or less respectively, calculated as Na.sub.2 O, SO.sub.3, Fe.sub.2 O.sub.3 and SiO.sub.2 and having a purity of 99.6 wt. % or more exhibits superior activity and selectivity when used in the dehydration reaction of ethanol to ethylene. By adding to the above mentioned high purity activated alumina catalyst a phosphate of one member selected from the metals of Group IIa, Group IIb, Group IIIa and Group IVb of the Periodic Table in an amount of from 0.05 to 5 wt. % of said catalyst there can be obtained a catalyst having more improved activity and selectivity as well as more increased mechanical strength.
