- CNG/LPG发动机尾气催化剂
- Catalysts for CNG or LPG powered engines
针对CNG/LPG发动机欧IV，欧V及以上排放标准，威孚开发了不同应用条件下的催化剂，适用于稀燃（Lean-burn)及当量燃烧天然气发动机（Stoichiometric gas engines）。本技术采用独特的稀土材料作为助剂，使用少量的贵金属，利用陶瓷载体或铁-铬-铝合金载体骨架，对尾气中难以氧化的甲烷碳氢（CH4）具有低起燃温度、较高的催化转化效率。
To meet Euro- IV/V and above emission standards for CNG/LPG engines, Weifu has developed catalysts under different application conditions, which are applicable to lean-burn and stoichiometric gas engines. These catalysts with rare earth as additives and small amount of precious metal coated on ceramic or metallic substrates have low light-off temperature and high conversion rate for CH4.
