Ultraviolet photocatalyst is a part that stops working by light. It is separated from the exhaust pipe of the initiator and oxidized to reduce the emission of pollution. They have made great contributions to the exhaust gas pollution. Not only that, but there are many other uses. Perhaps some people have little understanding of the photocatalyst. So let's take you to understand the main uses of the UV photocatalyst. What substances do you put in?
At the same time, it can effectively reduce HC, CO. oxidation catalysts can remove 90% of SOF in exhaust gas, thus reducing PM emissions by 40%~50%. The efficiency of HC and CO disposal can reach 88% and 68% respectively. Catalytic oxidation technology has good effect on removing soluble organic components (SOF) from diesel particulates, that is, adding catalytic converters in diesel exhaust system.
SOF can be removed by oxidation reaction of noble metal catalysts such as platinum, rhodium and palladium or rare earth catalysts. Usually, the removal efficiency of SOF can reach 80%. At the same time, harmful substances such as HC and CO in tail gas can be removed. However, the removal efficiency of carbon particulate matter by this technology is poor, and the catalyst can convert SO2 in exhaust gas into SO3.
The tendency of sulfate particle formation, especially at higher temperature, increases the rate of sulfate formation, which makes the total amount of particulate matter emission decrease slightly. Moreover, the presence of sulfide also makes catalyst poisoning deteriorate. Therefore, diesel particulate catalytic oxidation technology is generally applicable to diesel fuels with lower sulfur content.
