ABSTRACT:
A method for enhancing ethylene yield in the conversion of oxygenates to olefins that involves extracting molecular sieve catalysts, such as silicoaluminophosphate catalysts, with a mineral acid is provided. Acid extraction is thought to alter the crystallinity of the molecular sieve catalyst and thereby improve ethylene yield.
