US 5,374,405 A · Rotating fluidized bed reactor with electromagnetic radiation source

Abstract

A rotating fluidized bed reactor in which inert solid particles are held in place by centrifugal forces. The reactor includes a rotating porous bed vessel drum within a plenum vessel and the drum rotates to hold the solid particles at the side thereof. Gas is introduced through the walls of the drum and can be drawn off at the top. An electromagnetic radiation source can be included within the drum for promoting photochemical reactions. The solid particles can be inert particles that are loaded with reactant which reacts with the gas stream and/or from the electromagnetic radiation. In other embodiments of the invention, the particles do not contain reactant and reactant is provided within the gas stream only. Such a rotating bed reactor is suitable for use with both batch and continuous flow through processes.

Dependent claims

A rotating fluidized bed chemical reactor, comprising:

plenum means for delivering gas to a rotating fluidized bed;
drum means, rotatable about a rotation axis thereof containing solid particles for a rotating fluidized bed, the drum means having an annular wall defining an inner surface and an outer surface, the annular wall positioned annularly around the rotation axis;
the plenum means and the drum means being constructed and arranged so that the plenum means can deliver gas to the outer surface of the annular wall and the annular wall is constructed so that gas from the plenum means will pass through the annular wall;
the drum means including a gas outlet so that gas from the plenum means that passes through the annular wall will exit from the gas outlet;
and
radiation means for providing electromagnetic radiation to the interior of the drum means from within the drum means.
