摘要
The catalytic performance of Nb doped Co-Al2O3 was investigated for the selective catalytic reduction of NO, in diesel engine exhaust using light gas oil as a reducing agent. Since, the hydrocarbon (HC) conversion over Co-Nb/Al2O3 was lower than that over Co-Al2O3 above 600 degreesC, the excessive combustion of the reducing agent was depressed over Co-Nb/Al2O3. Then, the NO, conversion over CoNb/Al2O3 was higher than that over Co-Al2O3.
