摘　　要：用浸渍法制备了Cu-K-V/Mo/ZrO2-Al2O3催化剂,利用催化剂活性评价考察了其对柴油车尾气中颗粒物的催化活性,研究了Sn-Cu-K-V/Mo/ZrO2-Al2O3催化剂抗硫中毒能力.结果表明,在未加入SO2时,Sn-Cu-K-V/Mo/ZrO2-Al2O3催化剂对颗粒物的燃烧有较好催化活性;加入SO2后,该催化剂不但没有出现硫中毒,其催化活性反而有所提高,表现出较好的抗硫能力.Cu-K-V/Mo/ZrO2-Al2O prepared by immersion method and tested as a potential catalyst to be used in a diesel engine exhaust. And its anti-sulfur-poisoning property also was studied. The catalyst presented a good soot combustion activity without SO2. When the feed gas contained high concentration SO2, the SO2 could promoted the particulate matter combustion.
