Abstract:The formation of carbonate-like compounds in adsorption of CO2 on Na-A zeolite does not determine the type of changes in the heats of adsorption for degrees of filling of >1 molecule per unit cell (UC). The results of studies of the electrical properties of Na-A zeolite confirm the concepts that Na+ located in the eight-member rings are not the primary adsorption sites with respect to CO2.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 6, pp. 1238–1243, June, 1990.
