Abstract: Interest in coal’s photo-oxidation has grown rapidly for it is a very important method to the application of coal cleanly and high additional value. The photo-oxidation of coal is studied on the condition of ultraviolet light and oxygen by photoreaction device which made by ourselfs. Five factors are selected as discussion for the photo-oxidation of coal. It is found that the oxygen flow affects the initial reaction rate of coal’s photo- oxidation, 30ml/min oxygen can eliminate the influence of external diffusion. Select ultrafine coal can eliminate the influence of internal diffusion. Coal’s photo-oxidation rate increased with increasing light intensity and temperature. The result also shows that coal’s photo-oxidation rate increased with the decreasing particle size. Vitrain has more photo reactivity than fusain but initial reactivity takes on contrary changes.
