The experimental analysis method has the advantages that a coal microwave wide-frequency-band actual dielectric constant measurement method is established by means of combining measured data with theoretical conversion, and then dielectric property measurement is conducted on the basis of integrating existing analysis means with sample preparation methods for preparing various powder samples comprehensive in property, so that comprehensive studies on coal microwave dielectric response characteristics are achieved; comprehensive studies on microwave desulfurization mechanisms and coal quality change are achieved by means of combining microwave desulfurization experiments with industrial analysis, component determination, coal quality analysis and functional group and sulfur occurrence mode detection, and finally, comprehensive studies on the coal microwave response characteristics are achieved.

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...
