碩士 === 中原大學 === 環境工程學系 === 107 === Nitrogen oxides are gaseous pollutants, which are the cause of acid rain and precursors of chemical fumes, which also lead to an increase in the amount of ultraviolet radiation. Activated carbon is a product of high specific surface area, so it has good adsorption capacity and is widely used to remove contaminants.
In this study, carbon spheres were prepared by hydrothermal synthesis. Activated carbon was prepared by using different proportions of K2CO3. The specific surface area of activated carbon AC3:1 (K2CO3: activated carbon) was 1909.4 M2/g, and the pore size was 2.554 nm. 50nm). In the particle size analysis results, the pore size of 0.149~0.25mm accounts for 35~38%, the pore size of 0.106~0.149 mm accounts for 43~47, and the pore size of 0.106mm is about 17~18%.
Activated carbon AC3:1, AC1:1 and commercial products for adsorption test, take 1g activated carbon, flow rate 500mL / min, adsorption test for NOX concentration 1200ppb and 4600ppb, A3:1, AC1:1 and city prepared in this study The initial removal efficiency of activated carbon sold differs by 6 to 9%, but the removal efficiency differs by 17 to 23% at 5 hours, and the cumulative adsorption capacity of AC3:1 is 66% more than that of commercially available activated carbon. A3:1, AC1:1 differs from the initial removal efficiency of commercially available activated carbon by 1~3%, but the removal efficiency at 5 hours is 12.6~27.7%, and the cumulative adsorption capacity of AC3:1 is 49% better than commercial activated carbon.
