This patent describes process to produce methyl-tert-butyl-ether by reacting isobutene and methanol in an ether forming zone in the presence of a catalyst under ether forming conditions. The process comprises: passing an isobutane containing stream and steam into contact with a reforming catalyst comprising a catalyst base and a Group VIII metal in an isomerization and reforming zone at a temperature in the range of 950{sup 0}F to 1150{sup 0}F, to convert at least some of the isobutane to isobutene; withdrawing a reaction effluent from the isomerization and reforming zone; passing at least a portion of the reaction effluent into an ether forming zone and reacting therein isobutene with methanol in the presence of an ether forming catalyst to form an methyl-tert-butyl-ether, withdrawing methyl-tert-butyl-ether containing effluent from the ether forming zone and passing the effluent to a separation zone, separating in the separation zone and ether containing effluent into a methyl-tert-butyl-ether containing product stream a 1-butene containing stream, and a 2-butene containing byproduct stream, passing the 1-butene containing stream into the isomerization and reforming zone and into contact with the reforming catalyst such as to convert at least a portion of the 1-butene in the 1-butene containing stream and form 2-butene which is withdrawn from the separation zone as the by-product stream.
