Abstract

The γ-Al2O3 compound is generally not effective enough as catalyst, one of which is due to the low catalyst activity so that it is unable to break down the reactant into conventional fuel fractions. The sol gel process applied to form γ-Al2O3 and Pd/ γ-Al2O3 powders at a calcination temperature of 350 oC for 2 hours and a sintering temperature of 450 oC for 4 hours produces homogeneous Pd/γ-Al2O3 and γ-Al2O3 powders and nanoparticles. These two materials can be used as catalyst support materials because they have adequate adsorption and desorption power where Pd/γ-Al2O3 has a DA micropore volume (0.097 cc/g), pore volume (0.387 cc/g) and pore radius (46,868 Angstrom) which are greater than gamma. The Pd metal surface has the ability to bind substances will react to form reactive species. These metals accelerate gas reactions by forming weak bonds between gases and metal atoms on the surface. This process is called adsorption. The gases bound to metal surfaces react more easily than gases in the air. After the reaction occurs, the reaction products are released bond to the metal surface. This process is called desorption.
