Catalytic Activity in the Hydrocarbon Conversion of Systems Containing Platinum,Nickel,Iron,and Zinc Nanoparticles(Communication 2)

摘要

The catalytic activity of metal-containing zeolites modified by nanosized Pt,Ni,Fe,and Zn powders was studied in the process of upgrading the petroleum straight-run gasoline fractions.It was found that the introduction of metal nanoparticles into the zeolite increases the catalyst activity and allows the desired product to be obtained at a lower processing temperature.An enhancement of the aromatization reactions of the hydrocarbon feedstock was revealed on the catalyst samples deactivated in the first reaction cycle and calcined in air.
