CuO-ZnO-La2O3/activated carbon (AC) adsorbent was prepared and used for efficient adsorption removal of PH3 at various temperatures in the presence of O2. The feasibility of water and thermal regeneration of a spent CuO-ZnO-La2O3/AC adsorbent was also investigated. The influences of regeneration temperature, water concentration and calcination time were done on the spent CuO-ZnO-La2O3/AC adsorbent...
Phosphine (PH3) is one of highly toxic air pollutants, commonly produced in phosphorous chemical industry. In order to utilize high concentration CO in yellow phosphorus tail gas, metals (Cu, Fe and Ce) loaded activated carbon adsorbents were prepared for the adsorption of PH3 in this study. The operating conditions, such as oxygen content, adsorption temperature and space velocity, which influenced...
