The selective deactivation of acid sites located near the outer walls of the zeolite was studied . Silane catalytic cracking (ccs). By means of ir fourier analysis, the types of adsorption of silane compounds on the acid sites of the zeolite during the calcination period were well analyzed. Also, the effect of types of silane compounds on changes in the properties of the zeolite, including the amount of adsorbed ammonia and benzene in the zeolite, was investigated before and after the ccs treatment. The ccs method using diphenylmethylsilane (dpm-silane) proved to be effective for the deactivation of acid sites located near the outer walls of the zsm-5 zeolite. Synthesis of olefins from acetone was carried out using zsm-5 zeolite catalysts. Zeolite zsm-5 after ccs pest control with dpmsilane showed high selectivity for olefins, but also low selectivity for aromatic compounds.
