CNG Natural Gas Exhaust Catalyst Ceramic Substrate Euro 4/5/6
CNG(Natural Gas Exhaust Catalyst)
WEIFU has been engaged in the development and manufacturing of catalysts for a wide range of applications that protect the air we breathe. Catalyst expertise helps WEIFU become the leading catalyst supplier in China.
This CNG technology uses WEIFU's patented washcoat technology, which precisely places the precious metals within the washcoat, resulting in several important benefits:
Optimal use of precious metals
Lower cost and higher effectiveness
Higher conversions of CO, HC and NOx over a wide range of conditions
Performance of WFEC CNG catalyst:
--- Three-way window is relatively wide;
--- Conversion efficiency is high, with over 95% conversion efficiency of CH4, NMHC and NOx, and over 90% conversion efficiency for CO;
--- The ignition temperature is low, while featuring favorable hydrothermal stability and strong sulfur resistance.
With nearly 20 years of technology accumulation, we can provide customers with rich customized solutions. CNG catalyst can meet Euro-VI and China-VI regulations. CNG catalyst has been mass produced and successfully applied on more than 50 different domestic and foreign engine projects meeting China-VI emission standard.
