The method of converting n-butylenes to isobutylene by a skeletal isomrization reaction wherein said reaction is carried out at a temperature of between 300.degree. C. and 650.degree. C., under a pressure of between 0.1 and 100 atmospheres and a space velocity of said n-butylenes of between 0.1 and 40 WHSV using a cagalyst comprising a zeolite binder selected frm the group consisting of alumina, silica, silica-alumina, clay and a combination thereof, said catalyst having a pore size of at least about 4.5 angstroms and the pore size structure is characteried by intersecting 10-member ring and 8-member ring channels.
A process for the skeletal isomerization of an n-olefin of from 4 to 12 carbon atoms to provide a branched olefin product which comprises contacting the n-olefin under skeletal isomerization conditions with, as skeletal isomerization catalyst, a zeolite present in a binder, said zeolite having a pore size of at least about 4.5 angstroms and a pore structure characterized by intersecting 10-member ring and 8-member ring channels.
