Abstract: The direct coal hydrogenation is a clean and efficient utilization of low rank coal for preparing high quality liquid fuels and chemicals. The isotope tracer technology has been widely used in the mechanism of direct coal hydrogenation. The isotope tracer technology is briefly introduced and the progress of its application in the reaction mechanism of coal hydrogenation liquefaction, coal hydropyrolysis and other direct coal hydrogenation is reviewed in this paper.
