高硫炼焦煤脱硫技术的研究

Study on desulphurization technology for cokemaking coal with high sulfur

研究了一种低成本高硫炼焦煤脱硫技术,研究表明,粒径为0.45～0.6mm的炼焦高硫煤,用2mol/L的NaOH溶液浸渍,再经700W的微波辐照1min后,脱硫率可达42.5%,而其结焦性能并没有受到影响,该技术作为一种实用技术,具有良好的应用前景。

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.
