Selective Catalytic Catalytic Converter Honeycomb SCR Catalyst
Product Introduction
Honeycomb ceramics suited for filter applications, as catalyst carriers or as heat storage media.
Honeycomb ceramic filter is widely used in the filtration of hazardous air pollutants, volatile organic compounds in the automotive paint，chemical industry，electronic manufacturing industry，metallurgy and foundry industries.
Honeycomb ceramic filter is made of mullite ceramic material with high-quality and high-density straight-hole mesh, which
makes it have high thermal shock resistance and high sintering temperature resistance. Its straight hole design ensures the
balance between flow and strength, effectively removes industrial waste gas and impurities, etc.
Seletive Catalytic Reduction SCR technology is one of the most cost-effective and fuel-efficient technologies available to help reduce diesel engine emissions. SCR can reduce NOx emissions up to 90 percent while simultaneously reducing HC and CO emissions by 50-90 percent, and PM emissions by 30-50 percent. SCR systems can also be combined with a diesel particulate filter to achieve even greater emission reductions for PM.
