摘　　要：煤焦油是焦化企业的主要化工产品,其产量对焦化厂效益有着重要影响.通过对多种炼焦煤资源的考察,找出影响单种煤焦油产率的若干因素,并分析比较了各煤种挥发分、黏结指数和有机显微组分含量等参数对其焦油产率的影响.结合多个参数定义一个新指标——焦油指数,使用该指标表征单种煤的焦油产率,准确度优于其他任何单一参数.根据上述研究结果提出了配合煤焦油产率的预测方法,即配煤的焦油产率可以通过各单种煤的焦油产率和配煤比例加权得出.Coal tar is the major chemical product of coking plant, so its yield has great influence on the benefit of coking plants. By studying different kinds of single coal, several factors such as volatile component, caking index and macerals were found to affect the tar＇s yield. The tar index which contained the above three parameters was first defined and was proved to be effective to characterize the tar＇s yield of single coal. According to above research, a new method was proposed to anticipate the tar yield of blending coal.
