(NiO, Ag /Fe2O3-Al2O3-bentonite) as promising catalyst for CO and HC removal from single-cylinder engine exhaust emissions

The catalytic oxidation of carbon monoxide (CO) and hydrocarbons (HC) is a very important process for maintaining health protection systems. So nickel and silver are widely used in heterogeneous catalysis. In this work, the activate of (NiO, Ag/ Fe2O3, Al2O3, Bentonite) based gasoline Oxidation Catalyst on the exhaust emissions of gasoline electricity generator was tested. Catalyst was confirmed by scanning electron microscope (SEM), Energy Dispersive X-ray (EDX) and nitrogen adsorption for determination of BET surface area. This catalyst (Ni, Ag /Fe2O3-Al2O3- Bentonite) exhibits superior catalytic performance in the oxidation of CO and HC, with air as an oxidizer. Maximum conversion in CO and HC emissions were obtained at the rate of 99% and 77%.
