Zusammenfassung:The invention discloses a high-specific-surface-area formed carbon material and a preparation method thereof. The carbon material has the following properties: the carbon material has micropore/super-macroporous dual pore channels, has three-dimensional through pore channels of 50-300 microns, has the specific surface area of 600-1500 m < 2 >/g, the crushing strength of 5-15 N/mm and the mass wear rate of less than 0.5%. The preparation method comprises the following steps: (1) mixing, stirring and kneading water, zymophyte, flour and an extrusion aid to obtain a plastic body; (2) sealing and storing the plastic body for a certain time, mixing and kneading again, extruding the plastic body into particles with specific shapes by adopting a banded extruder, and carrying out hydrothermal treatment under a closed condition; (3) drying and roasting a product subjected to hydro-thermal treatment in the step (2); and (4) activating the product in the step (3) with water vapor, and drying to obtain the formed carbon
