Considerable reduction in crystallization time in the preparation of a new type of zeolite catalyst for olefin synthesis from methanol

Abstract

A new type of zeolite catalyst for a highly selective (ca. 77%) synthesis of C2–C4 olefins from methanol has been prepared; the crystallization time at 187 °C may be made very short (2 h) using tetramethyl-ammonium hydroxide as the modifier.
