摘要：
The mechanism of sulfur retention by alkali and specific earth metals of corn straw and coal were experimentally investigated using thermogravimetric analyzer (TG) and gas chromatography and mass spectrometer (GC-MS), as well as the effects of different concentration of oxygen on alkali earth metal CaO sulfate. The results show that the existence of alkali metals can catalyze volatile content and coke combustion and react with SO2 to form steady sulfate. The desulfurization process of alkaline minerals is mainly divided into three phases: physical adsorption stage, chemical reaction control stage and diffusion resistance control stage, a single alkaline-earth metal CaO consistent with that. For the certain amount of desulfurization agent of CaO particles, the sulfate is not affected by the concentration of oxygen in the oxygen-rich conditions.
