Characterization of wet impregnation method for catalytic microcombustor by using platinum_Muhamad Nazri Murat, Muhamad Azman Miskam, Mohd Azmier Ahmad,

Abstract The wet impregnation method for catalytic microcombustor was characterized by using platinum as a catalyst. The main purpose of this stud y i s to increase the surface porosity of the catalyst support. A high surface porosity indicates that a high amount of catalyst was deposited within the surface areas. The performance of the catalytic microcombustor improves with increasing catalytic surface area. The stainless steel catalyst support was treated with sulfuric acid solution containing polyvinyl (3.89 w t%) and propargyl alcohol ( 1.48 w t%). Combustion test was performed using LPG-air to test the performance of the catalyst. The surface support treated with polyvinyl (PYA) showed a higher surface porosity and combustion blow-out limit compared with propargyl alcohol. The combustion mode changes from surface to submerged combustion after the catalyst was deposited in the support surface.
