摘要：
A process for the manufacture of a modified aluminosilicate zeolite is disclosed which includes contacting a starting zeolite in an aqueous phase with a dealuminating agent at a pH value of lower than 4 in the presence of a soluble silica. A novel zeolite composition is also disclosed which has increased acid and thermal stability.
