Two gasoline samples with different sulfur contents (equating to 150 μg/g and 50 μg/g of sulfur, respectively) were used to examine the durability and performance of catalytic converter on the bench test. The test results have revealed that in comparison to the influence of sulfur on ageing of catalytic converter the thermal ageing had a more remarkable impact on the performance of catalytic converter, and the performance of catalytic converter could be restored by high-temperature desulfurization process after ageing by the high-sulfur gasoline sample (containing 150 μg/g of sulfur) .展开更多
