This article presents results of a calculation of the structural parameters of the amorphous aluminosilicate that determine the strength of bead cracking catalysts, in accordance with the theory of strength of disperse porous solids. The compressive and impact strengths of the catalysts are determined by the properties of the matrix. The inclusions of zeolite or nonporous fillers create a new phase in the matrix, which prevents the growth of microcracks at the interfaces. The adsorption of moisture and hydrocarbons lowers the attrition resistance of the catalyst quite considerably, to a greater degree for the amorphous catalyst than for the zeolitic catalyst.
