Abstract:

Abstract：Coal carry mass of high-sulfur coal, in order to solve the desulfurization problems, the use of microwave irradiation to coal desulfurization was studied. Explore the raw coal moisture, graded, temperature of microwave irradiation on the influence of coal desulfurization, the experimental results showed that the coal desulfurization rate can be reached 23.25%. Through the IR spectra and XRD testing showed that the coal sample’s chemical structures become unstable after microwave irradiation, and chlorite and marcasite (FeS2) etc mineral crystal was disappear, turned into emery and magnetite etc mineral crystal.

Key words: Keywords：high-sulfur coal, microwave irradiation, desulfurization rate, mineral crystal
