ABSTRACT:
A process for the selective surface dealumination of organic-containing zeolites by contacting the zeolite with dicarboxylic acid, such as oxalic acid. The treatment results in a reduction in surface acidity without a significant reduction in overall activity. The organic may be a directing agent used in the zeolite synthesis or introduced into the pores of the zeolite after thermal treatment.
