摘　　要：为了研究干、湿法熄焦焦炭性能之间的差异,对武钢的干、湿法熄焦焦炭进行了常规、粒度、结构、强度、热性能、催化、光学组织等性能的对比分析研究。研究结果表明:与湿法熄焦焦炭相比,干法熄焦焦炭在平均粒度、粒度均匀系数、机械强度、热性能等方面均有明显改善;灰成分催化指数MCI、光学组织指数OTI基本不变;而吸碱能力强,抗碱能力弱,但是吸碱后的热性能仍优于湿法熄焦焦炭;吸硼能力弱、钝化效果差,钝化后干法熄焦焦炭的热性能稍低于湿法熄焦焦炭。In order to make clear the difference in properties of CDQ and CWQ cokes, the comparative study was carried out by analysis, on composition, size distribution, structure strength, thermal properties, catalysis and texture. The results show that, compared with CWQ coke, the properties of CDQ coke is much better in mean grain size, grain size uniformity, mechanical strength, thermal properties etc. , the ash content, catalytic index （MCI）, optical texture index （OTI） etc. are unchanged basically,and its alkali absorptance is strong, alkali resistance is weak, but its thermal properties are still superior to CWQ coke after alkali absorption,its boron absorptance is weak, passivation effect is bad, thus its thermal propetties is somewhat inferior to CWQ coke after boron absorption.
