ABSTRACT:
A process is provided to produce a 2-alkene product from a 1-alkene-containing feed stream. The process comprises contacting the 1-alkene-containing feed stream in a reactor zone to isomerize the 1-alkene-containing feed stream to produce the 2-alkene product. More specifically, a process is provided to produce a 2-butene product from a 1-butene containing feed stream.
