PHOTOCATALYTIC REACTOR AND METHODS OF USE
First Claim
1. An apparatus for carrying out a photocatalytic reaction on a liquid, the apparatus comprising:
- a reaction chamber having a longitudinal axis and comprising a fluid inlet and a fluid outlet displaced in a longitudinal direction of the reaction chamber;
a layer of mobile photocatalyst particlesa bearing surface for the layer of mobile photocatalyst particles disposed between the fluid inlet and the fluid outlet, such that in use a liquid to be treated flows between the fluid inlet and the fluid outlet and contacts the layer of mobile photocatalyst particles;
and further comprising at least one formation configured to redirect the flow of the liquid to be treated through the layer of mobile photocatalyst particles to agitate or mobilize the mobile photocatalyst particles.

Abstract
The present invention provides an apparatus and method for carrying out a photocatalytic reaction. The apparatus comprises a reaction chamber having a longitudinal axis and comprising a fluid inlet and a fluid outlet displaced in a longitudinal direction. A bearing surface is provided for a layer of mobile photocatalyst particles disposed between the fluid inlet and the fluid outlet, and a reactant fluid flowing between the fluid inlet and the fluid outlet contacts the layer of mobile photocatalyst particle. A formation is provided to redirect the fluid flow through the layer of mobile photocatalyst particles to increase the contact of the fluid with the layer of mobile photocatalyst particles.
