由于材料和结构的特性,与目前普遍采用的陶瓷、粘土催化剂载体相比,合金泡沫的传热特性更好,反应速度更快,转化效率更高。2013年7月1日,重型柴油车国Ⅳ排放标准如期实施。虽然在推行的过程中遇到重重阻碍,但不可否认的是,排放控制升级已是大势所趋。与此同时,全国各地多次出现的严重雾霾天气也再次将治污减排推向了风口浪尖。作为机动车排放“大户”的商用车尾 Due to the material and structural characteristics, the alloy foam has better heat transfer characteristics, faster reaction rate and higher conversion efficiency than the commonly used ceramic and clay catalyst carriers. On July 1, 2013, the national IV emission standards for heavy-duty diesel vehicles were implemented as scheduled. Although many obstacles have been encountered in the process of implementation, it is undeniable that the upgrade of emission control is the trend of the times. At the same time, severe haze and weather in many parts of the country have repeatedly pushed pollution control to the cusp. As a motor vehicle emissions “big ” commercial rear
