How much percentage of air pollutants emissions reduces by using catalytic converter on vehicles exhaust?3 answersThe use of catalytic converters on vehicle exhaust can reduce air pollutant emissions by a significant percentage. Studies have shown that the maximum reduction in CO2 emissions can be up to 42.85%. The reduction in CO emissions can reach up to 83%. Additionally, the use of catalytic converters can lead to a reduction in HC emissions by up to 18.4%. Another study found that the highest reduction in CO levels was achieved at an engine speed of 2000 rpm, with a reduction of 5.23. The highest percentage reduction in HC levels was observed at an engine speed of 1000 rpm, with a reduction of 645%. These findings demonstrate the effectiveness of catalytic converters in reducing air pollutant emissions from vehicle exhaust.
What is the role of catalyst converters in the reduction of greenhouse gas emissions?5 answersCatalytic converters play a crucial role in the reduction of greenhouse gas emissions. They are used to convert carbon dioxide (CO2) into chemicals that can serve as energy vectors in a carbon-based energy cycle. These converters utilize redox catalysts with high turnover number, selectivity, and efficiency to overcome the stability of CO2. The reduction of CO2 requires catalysts in various reaction modes, such as electrocatalytic, photoelectrocatalytic, or photocatalytic. Mechanistic studies are important for understanding the detailed mechanisms of CO2 reduction and guiding catalyst design. The catalytic conversion of CO2 into clean fuel and value-added chemicals is a promising approach to address greenhouse gas emissions and energy shortage. Catalysis will play a critical role in reducing the flow of greenhouse gases into the atmosphere, and various catalytic processes, such as water electrolysis, steam reforming, and biomass waste transformation, are being explored for this purpose.
