【 摘 要 】

This study investigated the promotion of steam for CaO adsorbing SeO2gas at the medium temperature interval (240°C-800°C), based on the previous studies on CaO adsorbing SeO2gas. The experiments revealed both the influences of temperature and steam concentration. The mechanism of the promotion is similar to those of steam in carbonation and is confirmed by a series of designed experiments and characterization of the products of gaseous SeO2adsorption.
