SYNTHESIS AND PROPERTIES OF BEA/MOR CO-CRYSTALLINE ZEOLITES
The paper deals with the method of BEA/MOR co-crystalline zeolites preparation as a result of Beta (BEA) and Mordenite (MOR) zeolites hydrothermal co-crystallization from the initial alumosilicate gels of the following mole composition: xNa2O • yТЕАBr ∙ Al2O3 • zSiO2 ∙ nH2O (where x=3-8; y=7-10; z=10-25; n=500-600). Obtained BEA/MOR co-crystalline zeolites have been used for the preparation of n-hexane medium temperature isomerization catalysts. BEA/MOR co-crystalline zeolites are shown to be more effective in n-hexane isomerization than mechanical mixtures of BEA and MOR zeolites of similar phase composition.
