| 摘 要： | 通过添加负催化剂的无机酸(A)、氧化物(B)和单质(C)到配煤中炼焦的方式把负催化剂负载到焦炭中，研究了它们对所得焦炭热性质的作用．结果表明，无机酸(A)和氧化物(B)使焦炭冷热强度均下降，单质(C)加入煤中炼焦，无论对单种煤或是配煤，均能明显改善焦炭热性质，且在所研究的范围内，随着加入量的增大，热性质改善增大；对焦炭热性质越差的焦炭。单质(C)对其改善的程度越大．

| Abstract: | Adding negative catalysts as inorganic acid(A),oxide(B) and simple substance(C) into blending coal,thereby adding them into coke through coking process,the effects of negative catalysts on thermal property of coke was investigated.It indicates that the former two make both cold and thermal strength decreasigng,while simple substance(C) improves the thermal property of coke for both simple and blending coal.Additionally,within the scale studied,more the amount added was,more thermal property improved was;worse the thermal property of coke was,bigger the extent improved by simple substance(C) was. |
