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.
