ABSTRACT:
An integrated process is disclosed that substantially reduces the cost of producing MTBE and other alkyl tertalkyl ethers by eliminating a major portion of the equipment and operating costs associated with the downstream processing of the etherification reactor effluent. The integrated process combines the process for the etherification of iso-olefins and methanol, or other alkanols, to produce methyl tertiary alkyl ethers such as MTBE and/or TAME with the catalytic process for converting feedstock such as oxygenates, light olefins and paraffins to higher molecular weight hydrocarbons. Unconverted reactants from the etherification reaction, which may comprise unreacted alkanol and unreacted hydrocarbons or just unreacted hydrocarbons, are separated from the product ethers and passed to the catalytic conversion process reactor for conversion to gasoline boiling range hydrocarbons.
