MANUFACTURE OF CRYSTALLINE ALUMINOPHOSPHOSILICATE AND MANUFACTURE OF HYDROCARBON USING IT AS CATALYST

摘要

PURPOSE:To obtain the titled compound suitable for use as a starting material for a catalyst used in the synthesis of lower olefin from methanol by bringing a starting material mixture contg. a P2O5 source for synthesizing zeolite into a hydrothermal reaction. CONSTITUTION:An SiO2 source (A) such as silica sol is mixed with an Al2O3 source (B) such as aluminum hydroxide, a P2O5 source (C) such as phosphoric acid, an alkali metallic ion source (D) such as sodium hydroxide, an org. crystallizing agent (E) such as tetrapropylammonium bromide or pyrrolidine and water (F) in prescribed ratios. The starting material mixture is hydrothermally treated by heating under reflux for about 1-30 days, and the resulting reaction product is separated by filtration, washed, and dried at about 100-120 deg.C to obtain crystalline aluminophosphosilicate having a composition represented by the formula (where M is an alkali metallic ion or a hydrogen ion, 0=50, and m= 1-x) when it is calcined at 500 deg.C.
