Abstract
A method is disclosed for modifying an aluminosilicate-containing inorganic solid having a predetermined ion exchange capacity and containing an extractable silica by contacting, in the absence of added organic nitrogen or organic phosphorous compound and added activating metal oxide, the porous solid with liquid water at a pH of at least 6, at a temperature of up to 370.degree. C. for about 1 to 100 hours, and recovering a crystalline solid having an ion exchange capacity greater than the starting inorganic solid.
