Abstract
A process for the decomposition of photocatically degradable organic material includes exposing the organic material to ultraviolet light as the material is passing across the surface of a spinning disc. The surface of the disc carries anatase titanium dioxide adhering to the disc. The anatase titanium dioxide acts as a catalyst in the degradation process and preferably has a high surface area. Organic materials such as hydrocarbons alcohols, acids, esters and others are destroyed by this environmentally acceptable process.
Claims13
A process for the oxidative decomposition of photocatalytically degradable organic material comprising exposing said organic material in fluid form to ultraviolet light and passing said organic material across a surface of a plate-like member which carries anatase titanium dioxide adhering to said surface, said member rotating about a central axis perpendicular to the radial plane of said member thereby accelerating said organic material radially outward of said axis across said surface of said member creating a high degree of turbulence and a mass transfer of atmospheric oxygen across the liquid/gas phase interface on said surface.
