Notes:
Abstract Three conventional methods of dealumination were tested on the alumina-rich Ca-A zeolite. The mild acid leaching and the hydrothermal treatment led to mesoporous materials with a sharp distribution of pore size in the 4 nm region. On the other hand, treatment with ammonium hexafluorosilicate resulted in materials with mesopores of 12 nm in size. The latter technique produced the best thermally resistant materials which exhibited also the largest void volume and the highest cation exchange capacity.
