Abstract

1340498 Synthetic mordenite SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 19 April 1971 [3 April 1970] 15942/70 Heading C1A Mordenite is prepared by heating an aqueous mixture comprising amorphous silica-alumina and one or more sodium compounds, in which process at least 70 mol. per cent of the sodium present in the starting mixture expressed as Na 2 O originates from sodium salts of polybasic acids having a pK value for the highest dissociation step measured at 18‹ C., which is larger than 10 and in which process the following relation exists between the Na 2 O/Al 2 O 3 molar ratio (m) in the starting mixture and the applied reaction temperature (t) which amounts at most to 160‹ C.: m=8À3-0À06(t-100)Œ2À3. Examples of suitable inorganic acids are arsenic acid, orthoboric acid, carbonic acid and phosphoric acid. The amorphous silica-alumina preferably has a silica/alumina molar ratio between 9À5 and 12À5 and is preferably either a cogel of aluminium hydroxide on silica hydrogel or a cogel of a commercial silica-alumina cracking catalyst. Preferably the reaction is carried out at 95‹ to 155‹ C. with agitation in an autoclave at autogeneous pressure. The crystals of mordenite separated from the mother liquid are washed with water and dried at 100‹ to 200‹ C.
