Abstract
A method for skeletal isomerization of linear olefins to iso-olefins, e.g., n-butenes to isobutylene, over a catalyst comprising medium pore zeolite, e.g., a zeolite selected from ZSM-22, ZSM-23, and ZSM-35. Treatment of the zeolite with dicarboxylic acid, e.g., oxalic acid, significantly reduces aging rate and increases cycle length of the catalyst.
