Abstract: The hydrodynamic performance of the bubble distributor in hydrogenation reactor was simulated by Fluent software. The downcomer and the stream breaker of the BL gas-liquid distributor. were optimized in structure. It was found that the spray area increases by 255% and the non-uniformity reduces by 30.19% after optimization, but the pressure drop of the improved distributor is 73.63% higher than the BL type distributor. The results indicated that the comprehensive performance of the new distributor is better than the prototype.

Key words: hydrogenation reactor, distributor, numerical simulation, structure optimization
