. Obviously, the metal loading was controlled at 3.0 wt%. After loading, compared with activated carbon, the BET surface area of supportedcatalysts decreased slightly, since the metal with big particle size partially blocked the micro-pores in the activated

(−10–65 °C), the reaction rate was found to be zeroth order with respect to CO and 0.2–0.3 order with respect to O 2 over Au/TiO 2 and Au/Co 3 O 4 . For the α-Fe 2 O 3 supportedcatalyst, on the other hand, the reaction orders for both reactants were

can be reused many times without significant loss of activity [ 1 – 6 ]. Such supportedcatalysts can be prepared by insertion of a ligand to an inert solid material and then using it as heterogenized ligand for the preparation of a supported metal

Generally, the bimetallic alumina supportedcatalysts (usually NiMo and less CoMo/Al 2 O 3 [ 28 ]) in sulfided form were studied for the HDO reaction of vegetable oils. There is still limited information available about the application of the non
create the demand for supportedcatalysts [ 14 – 22 ]. Zeolites, in most cases, have been chosen as suitable supports because of their high thermal and chemical stabilities and good crystalline structures [ 1 , 23 – 26 ]. These types of molecular sieves
