Integrated etherification and oxygenates to gasoline process
An integrated once through process for the production of ether-rich liquid fuels is described comprising: (a) reacting a fresh mixture of excess methanol in a hydrocarbon feedstock containing C/sub 4/+ isoalkenes in the presence of acidic etherification catalyst under etherification conditions whereby an etherification effluent stream containing methyl tertiary alkyl ethers is produced; (b) separating the etherification effluent stream to provide a first stream comprising ether-rich gasoline and a second stream comprising unreacted methanol and olefinic hydrocarbons; and (c) contacting the second stream with an acidic metallosilicate catalyst under olefinic and oxygenates conversion conditions at elevated temperature whereby C/sub 6/+ gasoline is produced.
