<p>An integrated process for the production of ether-rich liquid fuels containing MTBE and TAME (25) by etherifying (21) a hydrocarbon feedstock containing C4+ isoalkenes (20) in the presence of a stoichiometric excess of lower alkyl alcohol. Unreacted alcohol and olefins are passed to a zeolite catalysed conversion reactor (27) to produce gasoline (33) and light hydrocarbons (32). The light hydrocarbon fraction, comprising C4-C5 paraffins (32), is dehydrogenated (34) and C4-C5 olefins are recycled to the etherification reactor.</p> |
