摘　　要：利用焦油渣和酸焦油为原料,按一定比例混合,经70℃水浴加热处理制得型煤黏结剂,并确定该黏结剂在型煤中的最佳添加量。实验结果表明:添加10%该黏结剂生产型煤,抗压强度可达115.48 N/cm2,跌落强度可达97.88%的型煤,满足了型煤生产的各个阶段以及贮存、装卸、入炉的要求。同时使用该黏结剂制备添加无烟煤10%的型煤炼制焦炭可达到三级冶金焦.解决了焦化企业焦油渣和酸焦油污染环境的难题,具有一定的社会效益和经济效益。Using tar residues and acid tar oil as raw material,were mixed together according to a certain proportion and under 70℃water bath heat treatment to prepare the binder for briquetted coal.The results show that 10%of No.1 coal binder was blended to briquetted coal production.we get higher cold strength briquetted coal.Which the compressive strength can reach 115.48 N/cm^2,the falling strength can reach 97.88%,which can meet the strength requirement of briquetted coal in all stages of production,loading and unloading,and charging.Meanwhile it not only solves the environmental problem caused by tar residues and acid tar oil,but also has a certain comprehensive benefit.
