6、egeneratethecatalystandmaintainoptimumcatalystperformance.再生塔中的催化剂将通过四个区段：燃烧区、氯化区、干燥区以及冷却区。再生塔有两种运行模式：黑烧和白烧。在黑烧过程中，仅燃烧区含氧(0.5-1.0mol%)，而氯化区和干燥区却只含有氮。如果氯化区或干燥区有存在任何含焦催化剂的可能性，那么必须进行催化剂黑烧。一般在重新投用再生塔的情况下，采用催化剂黑烧操作。在白烧过程中，燃烧区含有0.5-1.0mol%的氧，而氯化区、干燥区和冷却区的含氧量是20.9mol%。再生塔一般在白烧状态

7、下运行。为确保完全达到催化剂再生和保持催化剂的最佳性能，必须采用白烧。DuringBlackburn,oxychlorination,anessentialcatalystregenerationstepperformedinthechlorinationzone,isnotcompleted.Oxychlorinationrequiresbothairandchlorideinjectionthuscanonlybeperformedduringwhiteburn.Oxychlorinationisnecessarytoproperly
