摘要
煤炭是我国能源的基石,其主体地位和作用难以改变,但煤炭燃烧带来的环境问题越来越严重,煤炭燃烧前脱硫能很大程度解决煤中硫元素的污染问题。文章综述了物理法、物理化学法、化学法和生物法等煤炭燃前脱硫技术,分析了各方法的适用范围、脱除效率和使用规模等,指出了煤炭脱硫过程中,应优先考虑燃前脱硫技术,同时将燃中、燃后脱硫技术作为辅助。
Coal is the cornerstone of energy in China,and currently,its principal position and role can hardly be changed.However,increasingly serious environmental problems are also caused by coal combustion.The desulfurization of coal before combustion can significantly solve the pollution problem of sulfur elements in coal.This paper reviews the technologies of desulfurization of coal before combustion,such as physical method,physiochemical method,chemical method and biological method,and analyzes the applicability,removal efficiency and capacity of each method.It is concluded that the technologies of desulfurization of coal before combustion should be given priority in the process of coal desulfurization,which can be supported by technologies of desulfurization of coal during and after combustion.
