本文论述了国外添加石油焦提高焦炭质量的研究动向。指出在强粘结性煤中添加一定量的细粒石油焦能减少焦炭的裂纹和孔隙率，降低焦炭的反应性，增加焦炭的机械强度和反应后强度，提高焦炭的块度，可满足铸造焦和冶金焦的质量要求。表明石油焦的添加量和粒度对焦炭性能有较大影响，并对石油焦的作用机理进行了讨论 This paper discusses the research progress of adding petroleum coke abroad to improve coke quality. It is pointed out that adding a certain amount of fine petroleum coke in strongly cohesive coal can reduce the crack and porosity of coke, reduce the reactivity of coke, increase the mechanical strength and post-reaction strength of coke, and improve the lumpiness of coke, Coke and metallurgical coke quality requirements. The results show that the amount and particle size of petroleum coke have a great influence on coke performance and the mechanism of action of petroleum coke is discussed
