The invention discloses a coke gasoline liquid circulation hydrogenation method for removing dialkene. According to the method, coke gasoline is introduced into a pre-removing tower after heat exchange, multiple hollow hydrogen distribution pipes and a pre-hydrogenation catalyst with large porosity are filled in the pre-removing tower; the contact positions between the hydrogen distribution pipesand the catalyst are provided with a large amount of fine holes; hydrogen overflows from the channels and is mixed with crude oil, the mixture goes through a pre-hydrogenation catalyst bed; the pre-hydrogenation catalyst bed adsorb impurities and pre-hydrogenate part of dialkene, part of hydrogen is dissolved in coke gasoline to form a liquid material with saturated dissolved hydrogen; after the liquid material with saturated dissolved hydrogen flows out the pre-removing tower, the liquid material is introduced into a reactor, the residual dialkene is hydrogenated and removed in the reactor inthe presence of a dialkene removal catalyst, after reactions, liquid-gas separation is performed, a part of obtained materials is taken as the product, and the other part is returned and mixed with the raw materials. The provided method has the advantages that the hydrogen utilization rate is higher, impurities and dialkene are removed more fully, and the catalyst service life is prolonged.
