摘要：
Gas-phase flow enhancement in the fluidized bed reactor (FBR) results in several serious issues include clotting phenomenon that is away from bubbling regime, turbulent regime, and transport. A secondary distributor was utilized for gas-phase distribution in the FBR to improve reactor performance. The experiments were carried out in a laboratory-scale bubble column. Effect of gas flow secondary distributor on bubble diameter was studied. The results showed that the bubble diameter was decreased of 50% by applying the secondary distributor. Therefore, a reduction in the bubble diameter led to the enhancement of gas-liquid phase contact and consequently increased reactor efficiency.
