摘要： An activated clay for treating aromatic hydrocarbons, containing montmorillonite in an amount of not less than 34% by mass, having an SiO2/Al2O3 mol ratio in a range of 3.8 to 8.0, and desorbing ammonia in an amount in a range of 0.11 to 0.20 mmols/g as measured by the ammonia TPD method with the heat of adsorption in a range of 128 to 148 kJ/mol. The activated clay comprises an acid-treated product of smectite clay, imposes no limitation on the area where the starting clay is produced, and features long catalytic life free of dispersion in the properties.
