A method is described for double bond isomerization of alpha-olefin-containing organic feedstock with minimal oligomerization which comprises contacting said feedstock under double bond isomerization conditions with a double bond isomerization catalyst comprising a zeolite having a Constraint Index of 1 to 12 whose surface has been at least partially deactivated for acid catalyzed reactions by chemisorption of an alkyl-substituted pyridine surface-deactivating agent which possesses an average cross section diameter greater than that of the zeolite pores.
