一、石油焦挥发份对沸腾氯化的影响高钛渣沸腾氯化生产四氯化钛,有的厂使用煅烧以后的石油焦,有的厂使用未经煅烧的石油焦(称之为3号焦)。我们在生产中对这两种石油焦都使用过,它们之间的最大区别是煅烧焦(如镇江产品)固定碳含量达95%以上,挥发份为0.8～2%;而3号焦的固定碳含量为76～81%,挥发份含量达 First, the impact of petroleum coke volatiles on the boiling chlorination High boiling titanium chloride production of titanium tetrachloride, some plants use calcined petroleum coke, and some plants using uncalcined petroleum coke (called No. 3 Coke). We have used both types of petroleum coke in our production. The biggest difference between them is that the calcined coke (such as Zhenjiang products) has a fixed carbon content of over 95% and a volatile content of 0.8 to 2% Carbon content of 76 ~ 81%, up to the volatile content
