VERWENDUNG VON MIT SÄURE EXTRAHIERTEN MOLEKULAREN SIEBKATALYSATOREN BEI DER UMSETZUNG VON SAUERSTOFFVERBINDUNGEN

摘要

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.
