ABSTRACT:
In a method of and apparatus for manufacturing methanol from methane a catalytic area is formed on the exterior of a hollow sintered stainless steel tube. Methane is maintained within the sintered stainless steel tube at predetermined pressure, and water continuously flowing across the exterior surface thereof strips the methane forming sub-micron sized methane bubbles. Ultraviolet light energy is directed onto the catalytic surface to form hydroxyl radicals from the flowing water. The hydroxyl radicals cleave the carbon-hydrogen bonds of the methane to form methyl ions which combined with the hydroxyl ions to form methanol.
