A Ru-La/ZrO2 catalyst was prepared by the precipitation method, in which Ru was an active component, La was a promoter and ZrO2 was a dispersant. Comparing with
The acidic modulations of a series of HZSM-5 catalysts were successfully made by calcination at different treatment temperatures, i.e. 500, 600, 650, 700 and 80
A series of supported molybdenum phosphide catalysts were prepared by impregnation method.XRD, TG-DTG, XPS and BET were used to study the phase, compositions an
