The zeolite framework composition codification by isomorphous substitution of aluminum atoms with the aim to improve catalyst selectivity have been used. The catalyst synthesized steadily worked during 19 hours with high (98-99%) selectivity at flow testing conditions.5481 Product Description popup.authors І.А. Манза А.В. Яковенко В.В. Іваненко К.І.
