Abstract

Ru/Al2O3 catalyst was prepared by standard impregnation method. The catalytic reforming performance of Ru/Al2O3 and commercial high nickel/low nickel catalysts on commercial No.0 diesel oil was studied. The regeneration method of carbon-deposited catalyst was also discussed. The results show that commercial low nickel catalyst has poor catalytic activity and stability for diesel, and increasing the water-carbon ratio can slightly improve the conversion rate of diesel. Increasing the reforming reaction temperature and adding methanol additives can effectively improve the catalytic activity of commercial high nickel catalysts. Ru/Al2O3 is a potential catalyst for diesel reforming, reducing the reforming reaction temperature can effectively prevent the catalyst from high temperature hydrolysis deactivation. Hydrogen peroxide has a good regeneration effect on Ru/Al2O3 catalyst.
