摘要：
Using a modified deposition-precipitation method, a series of Au-Mo/ZSM-5 catalysts with different Au loadings were prepared. The XRD, nitrogen adsorption-desorption, NH3-TPD, and TEM results showed that introducing gold significantly reduced the BET surface area and increased the acid content of the catalyst. The results of the catalytic cracking of light diesel oil showed that the conversion, micro-reactivity index, and propylene selectivity of the 1.0%Au-5%Mo/ZSM-5 catalyst were respectively by 3.59, 3.41, and 16.8% higher than those of ZSM-5.
