脱硫用煤质活性炭采用优质煤为原料，以先进的工艺设备精制而成。其外观为柱状颗粒或不定型颗粒状，具有很大的比表面积，合适的孔隙结构，机构强度高，能经受高温、高压作用，不易破碎，易于再生，使用寿命长等特点。
广泛应用于热力电厂、炼油、石油化工、化纤工业中的烟气脱硫，化肥工业中原料气脱硫，煤气、天然气脱硫及其它化学工业中的气体脱硫，是制作二硫化碳的**添加剂。
Desulfurization quality coal activated carbon from coal as raw material, advanced process equipment refined. Its appearance as the columnar grains or amorphous granular, with large surface area, pore structure, high institutional strength, able to withstand high temperature, high pressure, not broken, the ease of regeneration, and long service life.
Widely used in flue gas desulfurization in thermal power plants, oil refining, petrochemical, chemical fiber industry, chemical fertilizer industry in the raw gas desulfurization, coal gas, natural gas desulfurization and other chemical industry gas desulfurization, the best additive for the production of carbon disulfide.
