Abstract
A porous tube is positioned coaxially around and in axial alignment with a tubular lamp forming an annulus therebetween. Methane is directed through the porous tube and forms submicron size bubbles in a liquid flowing through the annulus. Energy from the tubular lamp generates hydroxyl radicals in the liquid which combine with the methane to form methanol. Photocatalytic material may be provided in the annulus either in the form of a layer of photocatalytic material formed on the interior surface of the porous tube or in the form of particles of photocatalytic material circulating through the annulus with the flowing liquid. A heat transfer apparatus may be provided in the annulus for removing heat generated by operation of the lamp.
