Abstract
An integrated process for the production of propene from a mixture of alcohols obtained by IBE (Isopropanol-Butanol-Ethanol) fermentation from at least one renewable source of carbon is disclosed. The process is characterized by dehydration of the alcohols in order to generate ethene, propene and linear butenes, respectively. The olefin mixture is then directed to an isomerization bed in order to generate 2-butene from 1-butene, followed by a metathesis bed to react ethene and 2-butenes to generate additional propene. This process exhibits a yield in carbon moles higher than 90% propene with respect to the alcohols produced in the fermentation step.
