<p>A method is disclosed for the double bond isomeriztion 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 chemisorption of a surface-deactivating agent, e.g., collidine, which possesses an average cross section diameter greater than that of the zeolite pores.</p> |
