BET-C (Brunauer-Emmett-Teller-Constant) was used to calculate the heat of adsorption (AHads) of nitrogen gas on the various catalysts. The well-known Brunauer-Emmett-teller (B.E.T) equation is used primarily to determine the surface area the physical adsorption of a gas on a solid surface. Surface area of catalysts was determined by using the basic principles of the adsorption theory fitted with the functions based on the BET adsorption model, the important data of BET-C can be shown in this study. Th value of the AHads (N2) for zeolite, Pt/zeolite, and Pt-Ce/zeolite calculated from the equation derived from BET-C are -6.43, -6.52, -8.78, -8.69, -9.71 and -9.52 kJ/mol, respectively.
