Is Hydrocracking Endothermic or Exothermic?

Hydrocracking reactions are the main sources of hydrocarbons (C₁, C₂, C₃ and C₄). The reactions are highly exothermic and consume high amounts of hydrogen. Cracking results in the loss of the reformate yield.

What is the difference between catalytic cracking and hydrocracking?

The basis of catalytic cracking is carbon rejection, while hydrocracking is a hydrogen addition process. Catalyst cracking uses an acid catalyst, while hydrocracking uses a metal catalyst on acid support. Another differnce is that catalyst cracking is an endothermic process while hydrocracking is an exothermic process.

Is catalytic cracking endothermic?

The cracking reactions are endothermic, and the heat necessary to heat the hydrocarbon to the reaction temperature and to supply the heat of reaction is provided by the heat of combustion from burning the coke from the catalyst.
