Abstract

N2 adsorption on the uniformly mesoporous material MCM-41, zeolite ZSM-5, and their mechanical mixtures at 77 K is reported. The use of the differential comparative method in the analysis of adsorption isotherms for this class of materials is complicated by the weak sorbate-MCM-41 surface adsorption interaction and, for adsorbent mixtures, by the compensation effect caused by the introduction of adsorption sites with an increased adsorption potential. Specific features of sorption on the two-component system are analyzed in the framework of the conventional BET model.
