Abstract

1,129,042. Crystalline aluminosilicate. MOBIL OIL CORP. 26 May, 1966 [28 May, 1965], No. 23655/66. Heading C1A. A crystalline aluminosilicate for use as a catalyst is prepared by heating an aluminosilicate containing mono- and/or divalent cations to 150-1700‹ F. to reduce the moisture content of the aluminosilicate to less than 90% of saturation and thereafter subjecting the aluminosilicate to base-exchange to reduce the content of said mono- and/or di-valent cations to less than 80% of their content prior to baseexchange. The starting aluminosilicate normally contains alkali metal cations, which have resisted removal in a prior base-exchange step with, for example, rare earth ions, and the aluminosilicate is heated in an atmosphere of steam, air-steam, nitrogen, flue gas, oxygen or hydrogen and then subjected to base-exchange, e.g. with rare earth or yttrium ions, to reduce the alkali metal content to 0À03-0À2 wt. per cent. The aluminosilicate may then be subjected to further heating, and mixed with relatively catalytically inert material for use as hydrocarbon conversion catalysts.
