Modification of pore size of MFI-type zeolite by catalytic cracking of silane and application to preparation of H2-separating zeolite membrane
Catalytic cracking of silane (CCS) is proposed as a new method for modifying the effective pore opening of a zeolite. In this method, first silane compounds which can penetrate into the pores of the zeolite are introduced and are pre-adsorbed on active sites within the zeolite, such as acid sites and metal cations. Next, the adsorbed species are cracked catalytically on the sites, leaving coke that contains Si atoms on the active sites. By the calcination of the coked material, mono SiO2 units are formed on active sites, thereby reducing the size of the pores. When this method is applied to powdery MFI-type zeolite, the adsorption capacity of benzene is markedly reduced, but that of CO2 is maintained constant. Furthermore, the proposed CCS method was applied to reduce the pore diameters of an MFI-type zeolite membrane. By use of the membrane, experiments of separating H2 from a mixture gas containing H2 and N2 or O2 were conducted in a flow system. The membrane showed a high H2 separation factor of about 90-140 (as compared with 1.4-4.5 for a non-treated MFI-type zeolite membrane).
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Application of 1941-30-6, you can also check out more blogs about1941-30-6
