A comprehensive study of the microwave dielectric response characteristics of coal was realized, and then a comprehensive study of the microwave desulfurization mechanism and coal quality changes was realized through the microwave desulfurization test combined with industrial analysis, component determination, coal quality analysis, functional group and sulfur occurrence form detection, and finally A comprehensive study on the microwave response characteristics of coal has been realized.

Description

technical field [0001] The invention relates to a research method of coal microwave desulfurization technology, in particular to a microwave response characteristic test analysis method of high-sulfur coal and sulfur-containing model compounds. Background technique [0002] Coking coal and fat coal, which play a skeleton role in the coking process, account for about 7.56% of the total coal in my country, and are scarce coals. With the continuous growth of steel consumption and the development of large-scale blast furnaces, there has been a serious shortage of high-quality coking coal, causing more and more coking enterprises to start using high-sulfur coking coal. Thereby affecting coke quality and steel quality, also brought serious environmental pollution. [0003] Coal microwave desulfurization technology is a new type of coal temperature purification desulfurization method developed in recent years. It is a method to achieve the purpose of desulfurization by using the d...
