Abstract
Crude alcohol streams are converted to olefins under reductive or non-reductive dehydroxylation conditions, in the presence of a halogen-based catalyst. The process includes autogenous gas pressure or a gas pressure from 1 psig (˜6.89 KPa) to 2000 psig (˜13.79 MPa), a temperature from 50° C. to 250° C., a liquid reaction medium, and a molar ratio of alcohol to halogen from 1:10 to 100:1.
