ABSTRACT:
A multi-bed, down-flow reactor includes several distributor assemblies, each having a centrally located mixing chamber and an annular collecting and mixing trough surrounding the mixing chamber. The mixing chamber has an inlet at one side thereof, an outlet in its bottom wall, and a quench gas inlet in its top wall above the outlet. A divider wall traverses the annular trough adjacent to the inlet to cause the pool of liquid collected in the trough to flow in a circular pattern around the mixing chamber to the inlet. This ensures that the liquid circulating through the trough is well mixed with the liquid raining down from the catalyst bed. Turbulent and spiraling flow patterns generated within the chamber further mix the liquid and gas and entrain quench gas in the liquid and gas stream.
