摘　　要：利用自主开发的团聚脱硫工艺,对两种复合药剂脱除高硫煤中微细粒黄铁矿进行了研究,并对两种药剂的协同效应进行了探讨.结果表明:两种复合药剂对脱除煤中的黄铁矿硫存在着很强的协同效应;实验得出两种药剂最佳配比为A2B2;在此条件下得到的精煤产率为70.08%,脱硫率为60.40%.说明采用该工艺可以在脱除高硫煤中黄铁矿硫的同时保持较高的精煤产率,且该复合药剂对煤样的团聚效果也比较好.By using the self-developed agglomerate desulphurization processing, the effect of two complex agglomerate reagents on removing fine slime pyrite from high sulfur coal was studied. The synergistic effect of the two reagents was also analyzed. Experiment results showed that there was an obvious synergistic effect of the two complex agglomerate reagents on the removal of pyritic sulfur. The best proportion of the two complex agglomerate reagents was A2Ba. The desulphurization rate of 60.40 % could be obtained at the best proportion, and the clean coal production rate could be up to 70.08 %. It is feasible to use the proposed technique to remove pyrite from high sulfur coal, and the complex reagents have an obvious effect on the coal agglomerate.
