| Research Abstract |
By using a combined method of IRMS-TPD of ammonia experimentand DFT calculation, the strong acidity and the catalytic activity observed were studied. Thus, three different conditions in which the catalytic cracking proceeded fast were observed ; i. e., the activity was related with the strong Lewis acidity, the enhanced Bronsted acidity, or the different reaction mechanism. The correlation between the acid strength and the activation energy for cracking was clearly observed on the HY based catalysts but not on the HZSM-5 zeolites.
