Microporous crystalline silico-alumino-phosphate composition, catalytic material comprising said composition and use of these for production of olefins from methanol

Abstract

Microporous crystalline silico-alumino-phosphate (SAPO) compositions, catalytic materials comprising the composition, and use of these for production of olefins from methanol. The catalysts contain silico-alumino-phosphate materials with AEI/CHA-mixed phase composition. The catalysts have prolonged life compared to those belonging to the prior art.
