| Summary: | 碩士 === 國立聯合大學 === 環境與安全衛生工程學系碩士班 === 103 === Air pollution from stationary sources and mobile sources. Mobile sources of the background In this study. Preparation Pt / Fe2O3-ZrO2 Catalyst simulate vehicle exhaust by Impregnation method, Pt concentration at a fixed concentration change its Supported. The use of CO, C3H8 and NO gas concentrations assess each catalyst conversion efficiency at 500℃. Use gas analyzer analysis on vehicle exhaust.
The results of this study show. PF0.4Z0.4 and PF0.5Z0.5 because the higher ZrO2 concentration lead to after calcination trace amounts particles to fall down reduce conversion efficiency In the first stage, and a space velocity of 62856hr-1 with a single gas conversion efficiency, in PF0.3Z0.3 as CO efficiency 100%, NO efficiency of 91.72% and 58.19% HC efficiency. Preparing a second phase of the experiment, the ratio of single gas still PF0.3Z0.3 the best conversion efficiency. While in the mixed gas to PF0.317Z0.267 removal CO of 98.43% efficiency, NO 94.33% efficiency and HC 87.83% efficiency, Because the mixed gas the reaction is at the moment, compared to a single gas lower dramatically HC conversion efficiency, and addition low concentrations of ZrO2 with its low cost.
The Institute prepared catalyst in a single gas, mixed gas, T50 and real vehicle exhaust of analog steam vehicle exhaust emissions the efficiency and removal of research and application. Can provide useful follow-up studies and contribution, and the results of the actual vehicle exhaust removal efficiency of simulation can also compare existing data Taiwan. As a reference to the Air Pollution Control Program.
