Catalytic process for the preparation of light olefins from methanol in a fluidised bed reactor

摘要

A method of preparing light olefins from methanol conversion by using a microspherical SAPO-34 zeolite in matrix as catalyst. This method comprises contacting methanol with a fluidized or moving bed of said catalyst. It is characterised where SAPO-34 zeolite is prepared from alumina, silica and a preformed template tetraethylammonium phosphate.
