| 摘 要： | 通过对石油化工中焦炭燃烧率的测定，考察了加入各种类别金属离子型助燃剂的对烧焦油线及焦炭燃烧图的影响，阐明了各种金属离子型助燃剂对焦炭的催化燃烧作用规律，并与煤的催化燃烧过程进行比较，初步探讨了焦炭的催化燃烧机理。实现表明：第四周期过渡金属离子型助燃剂的烧焦催化机理可以用氧传递过程来解释；IA族离子型烧焦助燃剂的催化效果显著，最适用于石油化工烧焦工艺。IA族与ⅡA族金属离子型助燃剂的催化烧炭机理可用生成易着火的正碳离子过程来解释。

| Abstract: | The effect of different types of ionic combustion supporting agents on petrochemical coke combustion was studied by determining combustion ratios. Comparing with coal combustion process, coke catalytic combustion rule and mechanism were clarified. Transition ionic catalyzer's catalytic function on coke combustion can be interpreted with oxygen transfer mechanism. IA ionic catalyzer has excellent catalytic function and is the most suitable catalyzer in petrochemical coke combustion. IA and IIA ionic catalyzer's catalytic function on coke combustion can be interpreted by the process of producing C + which is easier to be ignited. |
