提出了一种利用油团聚分选方法降低我国炼焦精煤灰分和硫分的新工艺，其特点是利用焦化过程的煤焦油经乳化后作为油团聚的团聚剂来分选经过超细磨后的重选中煤，再结合调整常规重选的分选密度，可大幅度地降低精煤的灰分和硫分。精煤团粒中的焦油在焦化过程中可以回收，降低了油耗。 A new technology for reducing the ash and sulfur content of coking coal in our country by oil agglomeration and separation method is proposed. The method is characterized in that the coal tar used in the coking process is emulsified to be used as the agglomeration agent for oil agglomeration, Re-election of coal, combined with adjusting the sorting density of conventional re-election, can significantly reduce the ash and sulfur content of clean coal. The tar in the pellets can be recovered during the coking process, reducing fuel consumption.
