Advance of the thermal decomposition of industrial by-product gypsum
摘要
Abstract
Thermal decomposition of industrial by-product gypsum is one of the most effective ways to recycle SO2 and the corresponding solid residues. The high cost,high energy-consuming,and low efficiency,seriously limit the reutilization of industrial by-product gypsum. This paper reviewed the recent advances on the research of thermal decomposition of industrial by-product gypsum. Based on the influence of atmospheric conditions,the ratio of reductant to CaSO4,the facilitation of addictive or impurity,and heating temperatures,the decomposition and desulfurization degree were analyzed. The advantages of microwave heating method were highlighted compared to conventional heating,and the decomposition mechanisms of CaSO4with C/CO were also summarized under different conditions. The research trend for thermal decomposition of industrial by-product gypsum in the future was discussed as well. The decomposition and desulfurization degree of industrial by-product gypsum can be effectively improved by optimizing reaction condition to reduce the high cost. The results showed that microwave assisted heating desulphurization of industrial by-product gypsum will be a promising direction for industry in the future.关键词
