Abstract

1,261,616. Zeolite of increased silica content. NORTON CO. 12 Nov., 1969, No. 55303/69. Heading C1A. A crystalline zeolite with an incrased SiO 2 to Al 2 O 3 mole ratio, preferably of at last 55:1 (i.e. Al 2 O 3 constitutes less than 3% by weight of the anhydrous material), is obtained by calcining a mordenite in the hydrogen-exchanged form or a precursor thereof at at least 350‹ C. but below 850‹ C., in the absence of steam and then leaching with acid. The leaching is preferably carried out with a hot mineral acid, optionally in the presence of tartaric or citric acid.
