Abstract
A process for regenerating spent zeolite composites. The process involves contacting the composite, either as a shaped article or a fine powder, with a caustic solution, e.g., sodium hydroxide at treating condition. Once the contacting is completed, the composite is isolated, washed with water, dried and calcined to give a regenerated composite.
