Abstract：Given the strategic demand for achieving the carbon peaking and neutrality goals,to get the maceral components efficiently separated is an effective approach for realizing clean,high-efficiency and comprehensive utilization of coal.The paper presents a detailed introduction to the properties and charac-teristics of maceral components,including vitrinite,inertinite and liptinite.Through study of the proper-ties of group maceral,the difference between the different components is brought to light,which provides a theoretical basis for their separation.It is proposed to separate maceral components using handpicking,screening,gravitational(centrifugal,heavy liquid cyclone),triboelectric and flotation methods.Ade-quate liberation of the components is an precondition for their effective separation.Because of the com-plexity of these components in form and distribution,some of the above-mentioned separation methods need to go some way before they can commercialized,and wait for further study in the future.
