Advances on the preparation routes to MSE -type zeolites, microporous silicates with a 12-10-10-ring micropore system, are reviewed and some examples of the catalytic application are presented. MCM-68 as the most typical aluminosilicate material with the MSE framework synthesized by using a rigid and bulky diquaternary ammonium cation as the organic structure-directing...
The effect of the SiO 22 O 3 ratio of H-mordenite on shape-selective catalysis was studied in the isopropylation of naphthalene with propylene. Aluminum concentrations at intracrystalline and external surfaces of H-mordenite are not directly related to catalyst performances. Dealuminated H-mordenite with a SiO 22 O 3 ratio higher than 30 exhibited high catalytic...
