Claim Text:
1. A process for the simultaneous dehydration and skeletal isomerisation of isobutanol to make substantially corresponding olefins, having the same number of carbons and including a mixture of n-butenes and iso-butene, said process comprising: a) introducing in a reactor a stream (A) comprising isobutanol, optionally water, and optionally an inert component, wherein the isobutanol is present in the stream (A) in an amount ranging from 30 to 100 weight percent based on a total weight of the stream (A), b) contacting said stream (A) with a catalyst in said reactor at conditions effective to dehydrate and skeletal isomerase the iso-butyl moiety of at least a portion of the isobutanol to make a mixture of n-butenes and iso-butene, c) recovering from said reactor a stream (B), removing water, the inert component if any and unconverted isobutanol if any to get a mixture of n-butenes and iso-butene, wherein the WHSV of the isobutanol is at least 1 h wherein the catalyst is:
