Research progress of coal microwave desulphurization

综述了煤炭微波脱硫的理论基础,介绍了微波脱硫技术的类型及研究进展,分析了煤炭粒径、微波功率、辐照时间、介电性质等因素对微波脱硫效果的影响.认为微波具有穿透性加热、选择性加热、无温度梯度等优点,是一种很有应用前景的煤炭脱硫方法,并展望了微波脱硫技术的研究方向.

This paper introduced the theoretical basis, the type, as well as the research progress of coal micro- wave desulfurization, and analyzed the influences on the desulfurization caused by the coal particle size, the microwave power, the irradiation time, the dielectric properties. It was considered that microwave is a desulfu- rization method of a great application prospect characterized by strong penetrability, high selectivity and no temperature gradient, and the paper also prospected the research direction of coal microwave desulfurization technology.
