چکیده انگلیسی
In order to provide comprehensive utilization of high concentration CO for mono-carbon (C1) chemical industry, the purification of yellow phosphorus off-gas is of great concern. In this research, activated carbon (AC) modified by different impregnants were used for removal of PH3, H2S, SO2, COS, and CS2 in yellow phosphorus off-gas. For the removal of PH3, AC impregnated with 0.10 mol Lâ1 CuAc2 was proved to be the best adsorbent. And removal efficiency of H2S could be significantly enhanced by AC impregnated with 7% Na2CO3. The results of plant experiments suggested that the total concentration of the impurities in yellow phosphorus off-gas was less than 1 mg Nmâ3 after purification operation. The metal-modified activated carbon (MMAC) was systematically characterized in terms of XPS, TGA, and DTA. The adsorption reaction mechanism was also investigated. As a result, the yellow phosphorus off-gas purified in this study can be used as a raw material gas in the C1 chemical industry.
