BENTONITE PILLARED BY MESOPOROUS SILICA AND ITS APPLICATION FOR GASOLINE TREATMENT

Vo Thi My Nga

Abstract


Di Linh bentonite was successfully pillared by mesoporous silica and this result had been published in previous reports. The acidity of this material was estimated by modern physico-chemical methods such as IR, TPD-NH3and the material was applied in the field of petrochemical catalysis. The acidity of the material has also been demonstrated by Cumen cracking at low temperatures about 350 °C with benzene conversion of 36.46 % and benzene selectivity of 73.98 %. In addition, the gasoline yield of silica mesoporous material pillared bentonite had got more twice higher than the one when using a mixture of bentonite powder and MCM-41 powder in the cracking Wax. This result confirms that the bond formation between bentonite and mesoporous silica when using one-step method, which increase  acidity of the synthesized material.
