摘　　要：粉状石油焦造球后,研究了煅烧条件对煅后焦实收率和真密度的影响。结果表明,粉状石油焦造球可提高煅后焦的实收率和真密度,降低煅烧损耗,改善煅后焦质量;升温速率、煅烧温度和煅烧时间均对煅后焦实收率和真密度有影响,可通过控制煅烧条件来降低生产成本,改善煅后焦的质量。Powdered petroleum coke was pelletized,and the effect of calcination conditions on the recovery efficiency and true density of calcined coke was investigated.The results show that pelletizing can improve the recovery efficiency and true density of calcined coke,reduce the calcination loss,and improve the quality of calcined coke.Heating rate,calcination temperature and calcination time can affect the recovery efficiency and true density of calcined coke.The production cost can be reduced and the quality of calcined coke can be improved by controlling the calcination conditions.
