The invention belongs to the technical field of petroleum processing, and more specifically relates to a method used for recycling reaction energy. According to the method, a main air blower is used for increasing the operation pressure of an entire reaction-regeneration system, a smoke machine is used for realizing output of more electric energy, an added reaction oil-gas turbo expander is used for recycling reaction oil-gas pressure energy and high temperature segment heat energy, the recycled energy is outputted, or is used for driving a rich gas compressor or used for electricity generation; the second law energy efficiency is much higher than that of waste heat boilers and recycled oil slurry steam generation. According to the method, only a reaction oil gas inlet main fractionator oil transfer line is provided with the turbo expander, so that the method is suitable for old equipment modification and new equipment construction. No influence on pressure balance and heat balance of the reaction-regeneratio
