The authors are studying on a new shower cleaning system of removing environmental pollutant materials from an exhaust gas. In this report the decomposition of the collected chemical pollutant materials by photocatalysis was experimentally investigated by using ethylamine as a specimen. The chemical reactor was composed of coaxial cylinders between which the packed bed of glass beads coated by photocatalyst was fixed, and "Black Light" was installed on the center of the cylinders to radially emit ultraviolet rays. The dependency of the decomposition rate of ethylamine was investigated on the radial thickness of the packed bed, the intensity of ultraviolet rays and the flow rate of ethylamine-water solution. It was found from the experimental results that the decomposition reaction is rate-controlled by diffusion and has a dependency of Re^<0.6>.
