Cu KFI Cu-CONTAING KFI ZEOLITE AND METHOED FOR MANUFACTURING THE SAME

摘要

A highly crystalline Cu-containing KFI zeolite and a process for its preparation are provided. The highly crystalline Cu-containing KFI zeolite contains Cu and Al ₂ , and the Cu / Al ₂ molar ratio is 40 to 80%. The process for preparing the highly crystalline Cu-containing KFI zeolite comprises the steps of preparing a base zeolite, preparing a metal cation and a hydroxide ion solution, mixing the base zeolite and the solution to form a zeolite mixture, Heating to form a crystallized zeolite, and providing Cu to the crystallized zeolite.
