Is catalytic cracking generally an exothermic reaction or an endothermic reaction?

Overall, it’s not good at all. The reaction is endothermic, while regeneration is exothermic. :lol

Catalytic cracking reactions are generally endothermic; among them, hydrogenation and isomerization reactions are exothermic, while cracking and aromatization reactions are endothermic. Essentially, the chain-breaking reaction of heavy feedstocks is an endothermic reaction

Generally speaking, I think it is an exothermic reaction, especially in the case of heavy oil catalytic cracking.
