    Abstract

    The effect of addition alkaline earth metals on the physico-chemical properties of M-Sn-O/α-Al2O3 and M-Pb-Sn-O/α-Al2O3 catalysts is studied. The formation of metal metastannates in theM-Sn-O/α-Al2O 3 system facilitated the growth of selectivity of the catalysts. Addition of alkaline earth metals into the Pb-Sn-O/α-Al-2O 3 composition resulted in stabilization of lead in the 4-valent state with formation of metal ortho-plumbates and a decrease in the selectivity for C2 hydrocarbons. The linkage between the basicity of the surface and the catalytic properties of the samples was established.
