Study of alkylation on a Lewis and Brønsted acid hybrid catalyst and its industrial test
چکیده انگلیسی

A novel catalyst ZnBr2 modified bentonite is prepared. Pyridine adsorbed FTIR spectra demonstrated the amount of Brønsted and Lewis acid was improved to 2 and 5 times, respectively. Thermal analysis indicated the thermal stability of ZnBr2-bentonite could reach 350 °C. Mechanism research led to an interesting hypothesis that in the former stage, the active position is Brønsted acid sites and in the later stage, both Lewis acid and Brønsted acid sites act as active positions. Industrial test showed the ability of ZnBr2-bentonite to remove olefins is 17 times higher than that of bentonite, and the industrial application prospect is good.
