Effect of the Structure and Acidity of Micro-Mesoporous Alumosilicates on Their Catalytic Activity in Cumene Cracking

Micro-mesoporous alumosilicates derived from zeolite ZSM-5 were obtained in dual template reaction media and in the presence of dual functional templates. It was shown that aluminosilicates with 0.15-0.25 zeolitization exhibit high catalytic activity in cumene cracking, approaching the activity of Z...

Description
Summary:Micro-mesoporous alumosilicates derived from zeolite ZSM-5 were obtained in dual template reaction media and in the presence of dual functional templates. It was shown that aluminosilicates with 0.15-0.25 zeolitization exhibit high catalytic activity in cumene cracking, approaching the activity of ZSM-5 and superior to ZSM-5 in total selectivity relative to the major products (propylene and benzene). Greater oligomerization of propylene is observed with increasing micropore volume and concentration of strong acid sites in the alumosilicates along with increased cumene conversion.
