Abstract
A benzene selective hydrogenation reaction system and a method are provided. The system includes a benzene refiner, a first hydrogenation reactor, a second hydrogenation reactor and a separator which are connected in sequence. The first hydrogenation reactor is provided with a first inlet and a first outlet, and the second hydrogenation reactor is provided with a second inlet and a second outlet. The first inlet is connected to the discharge port of the benzene refiner; the first outlet is connected to the second inlet; the second outlet is connected to the separator. The catalyst outlet is connected to the first hydrogenation reactor for recycling the catalyst into the first hydrogenation reactor. Two micro-interface units are respectively disposed within the first hydrogenation reactor and the second hydrogenation reactor, and the micro-interface units are used for dispersing and breaking hydrogen into micro-bubbles with a micron-scale diameter.
