Abstract
A process for the coupled production of alkyl tert-butyl ethers and butene oligomers from a mixture containing isobutane and n-butane. The isobutane is converted to the alkyl tert-butyl ether and the n-butane is converted to the oligomers. The ratio of the two reaction products may be controlled by setting the ratio of n-butane to isobutane appropriately by isomerization.
