provided is a reformate hydrotreatment method , the method comprising : under liquid phase hydrotreatment conditions , bringing the reformate and a catalyst having a catalytic hydrogenation effect into contact in a hydrogenation reactor , the hydrogen used in the hydrotreating process at least partially coming from the hydrogen dissolved in the reformate . according to the method of the present invention , the reformate separated from a reformate products separating tank can directly undergo liquid phase hydrotreatment ; therefore not only can the hydrogen dissolved in the reformate be fully utilized , but the olefins in the reformate can also be removed , while eliminate the requirements for recycle hydrogen and a recycle device thereof . the reformate obtained by the method of the present invention reduces the bromine index to below 50 mgbr 2 / 100 g , and has an arene loss of less than 0 . 5 wt %.
