Abstract

A flow distributor for a fluid bed reactor includes means for decreasing velocity of incoming liquid streams in a uniform, non-turbulent fashion. Inlet ports communicate with fluid portals having divergent walls to slow incoming flow. The fluid portals feed liquid flow to a plurality of diffusing flow paths provided between diffusion baffles positioned at the bottom of the reactor. The diffusion baffles may be prismatic shapes which are trapezoidal in cross-section with the broadest horizontal dimension at the bottom thereof. The diffusion flow paths therefore have divergent walls and act to further slow the liquid flow passing therethrough.
