贫煤与煤沥青共炭化研究

进行了不同配比的煤沥青和贫煤的共炭化研究，研究表明，煤沥青与贫煤共炭化时的相互作用是物理融合和化学相互作用的共同作用。其中物理融合表现在使焦炭界面结合状态改善，化学相互作用表现在煤沥青使贫煤的炭化性能发生变化。随煤沥青配比的增加，配煤黏结性有较大改善，焦炭OTI值增大，ISO值减小。煤沥青通过增大焦炭光学组织各向异性程度，使焦炭的反应性降低，反应后强度提高。

Study on co-carbonization of lean coal and coal tar pitch

The study on co-carbonization of coal tar pitch and lean coal with different blending ratios was conducted.The study showed that interaction of co-carbonization of coal tar pitch and lean coal was the coaction of physical bond and chemical interaction,in which the bond state of coke interface was improved by physical bond,and coal tar pitch varied the carbonization behavior of lean coal through chemical interaction with the increase of the blending ratio of coal tar pitch,the caking property of coal blend w...
