A process is disclosed for producing alkyl tertiary alkyl ether such as TAME from alkanol and hydrocarbon feedstock containing linear olefins, iso-olefins, linear alkanes and iso-alkanes such as C5 streams from FCC. The process selectively etherifies iso-olefins in a plural stage etherification zone whose linear olefin-containing effluent is treated by distillation to remove iso-alkanes, and alkanol before passing to a skeletal isomerization zone using constrained intermediate pore size zeolite catalyst such as ZSM-22, ZSM-23, or ZSM-35, which converts linear olefins to iso-olefins which are cycled for etherification. The use of distillation to remove iso-alkanes and alkanol reduces mass flow to the etherification process and minimizes skeletal isomerization catalyst poisoning by alkanol, without resort to water extraction processes which require subsequent treatment of the isomerization zone feed to remove water.
