Preparation of Au Supported ZSM-5 Catalysts and its Special Performance in the Catalytic Cracking of Butane Reaction

Abstract:

Au/ZSM-5 was prepared by improved desorption-precipitation (DP) method using urea as precipitant. Au-samples were characterized by TEM, UV-Vis, XRD, pyridine-FTIR, FTIR and the other techniques. The catalytic performance of Au/ZSM-5 catalysts was carried out on the catalytic cracking of butane by mini-scale pulse reactor. Results showed that: 2.0wt% loading Au/ZSM-5 catalyst obtained the best activity that the n-butane conversion rate comes to 58% by weight,60% olefin selectivity and 10% aromatics selectivity; the i-butane conversion rate comes to 53%, 35% olefin selectivity and 15% aromatics selectivity.
