A method is disclosed for the double bond isomerization of alpha olefin-containing feeds, e.g., conversion of 1-butene-containing hydrocarbon streams to 2-butene-rich product streams, wherein oligomer by-products are minimized. The process uses a catalyst composition comprising a zeolite whose surface has been at least partially deactivated for acid catalyzed reactions by treatment with an aluminum chelating agent, e.g., oxalic acid, which possesses an average cross section diameter greater than that of the zeolite pores.
