Abstract
A method is disclosed for preparing molecular sieves of the zeolite type, particularly A, X and Y, in massive bodies that exhibit higher crush strengths than observed for prior art massive bodies. Sized unreactive kaolin-type clay, a pore generating material, and preferably a set strength enhancing agent are mixed with water to a consistency that can be shaped into preformed bodies. In the cases of zeolites X and Y silica may be included in the mixture. These bodies are calcined, optionally aged, and digested to convert them to massive bodies containing the desired zeolite.
