Abstract:

 A low cost desulphurization technology for cokemaking coal with high sulfur is developed. The study reveals that after the cokemaking coal with grain size from 0.45mm to 0.6mm and high sulfur is impregnated with 2mol/L NaOH solution and irradiated with 700W microwave for one minute, the desulphurization rate can be up to 42.5%, while its coking property has no effect. The technology is used as a practical technology and has a good application prospect.
