探讨了采用经济型氧化配方氧化催化剂改装的重型天然气公交车在降低管制排放和非管制排放方面的性能。在规定的排放量中，一氧化碳的排放量减少了99%，碳氢化合物的排放量减少了62%，碳氢化合物的排放量减少了96%。催化剂配方有效地瞄准了排气中较低的链状挥发性碳氢化合物组分，这通常需要较高的起燃温度。总体而言，该催化剂使挥发性有机化合物的排放量减少了93%，并有效地将多环芳烃的排放量减少了46%。
The paper discusses the performance of heavy-duty natural gas transit buses retrofitted with economic oxidation formulation oxidation catalysts in reducing regulated and unregulated emissions. The regulated emissions exhibited a 99% reduction in emissions of carbon monoxide, a 62% reduction in emissions of hydrocarbons with the presence of the oxidation catalyst, and a 96% decrease in carbonyl compound emissions. The catalyst formulation effectively targeted the lower chain volatile hydrocarbon fraction in the exhaust, which generally requires high light-off temperatures. Overall, the catalyst produced a 93% reduction in emissions of volatile organic compounds and was effective in reducing PAH emissions by 46%.
