Popis: The best cracking catalysts in terms of service characteristics are those with particles in the shape of microbeads (microspheres) formed by spray drying. This article presents data on the influence of composition of the matrix, prepared from a mixture of pseudoboehmite and a natural component, on the shape of microparticles of series KN cracking catalysts. Two grades of a kaolinite clay from Troshkovo deposit were used a natural component. Pelletized specimens were used in determining the crushing strength of the catalysts. The results from these studies show that in order to prepare catalysts with spherical microparticles and high strength, it is necessary to use a semisynthetic matrix with pseudoboehmite not greater than 25% and alkaline-earth metals bringing the pH to a level above 7.5-8.
