Beschreibung
Zusammenfassung:	The invention discloses a micro-interface reaction system and method for diesel hydrogenation, which includes: a hydrogenation reactor, a plurality of sections of fixed beds are disposed in sequence from top to bottom in the hydrogenation reactor, and the plurality of fixed beds is filled with a catalyst; a micro-interface generator is disposed between the adjacent fixed beds, and a hydrogen inlet is disposed on the micro-interface generator. A side wall of the hydrogenation reactor is provided with a product outlet, and the product outlet is connected to a hydro-refining reactor for performing a deep hydrogenation reaction. A reaction product from a bottom of the hydro-refining reactor is passed into a gas-liquid separation tank for separating a gas phase containing hydrogen sulfide and hydrogen from the product, thereby obtaining the final product desulfurized diesel. By combining the micro-interface reaction system with the micro-interface generator, energy consumption is reduced for increasing productivity.
