Emission Testing of Catalytic Converter using Zirconium Oxide (ZrO) and Cobalt Oxide (CoO) as Catalyst

In today's scenario, the population of vehicles is increasing day by day. These vehicles are either running on gasoline or diesel engine. Due to abnormal combustion in SI and CI engine, the NOx, CO are the two major pollutants which emit from the exhaust. We can control this problem by pre-exhaust and after-exhaust treatment. Numbers of technologies like improvement in engine design, fuel pre-treatment, use of alternative fuels, fuel additives, exhaust treatment or better tuning of the combustion process etc. are being considered to reduce the emission levels of the engine. Among all the types of technologies developed so far, the most suitable after exhaust technique is the catalytic converter. This research work presents the characteristics of a new catalytic converter to be used for reduction of emissions. Others had designed and fabricated two types of catalytic converter, i.e. based on the material and type of wire mesh used. The present work aimed at using zirconium oxide (ZrO) and Cobalt Oxide (CoO) as a catalyst for catalytic converter. To determine the emission contents from LPG and Petrol, Eco- Gas Analyzer 100 was used. The experiment was conducted separately for both coated square type wire mesh and coated diagonal type wire mesh catalytic converter. From all the experimental data and graphical representation, it is observed that the reduction in pollution content, in case of coated diagonal wire mesh is much higher than that of coated square wire mesh type catalytic converter for both LPG and Petrol engine.
