Honeycomb carbon-based filter material and preparation method thereof

The invention provides a honeycomb carbon-based filter material and a preparation method thereof. The honeycomb carbon-based filter material has an integral honeycomb structure, honeycomb holes are uniformly distributed, and the distribution density is 1-8/cm < 2 >; the sizes of honeycomb holes are 0.5-8mm, and the specific surface area of the honeycomb body is less than 20m < 2 >/g. The preparation method comprises the following steps: (1) mixing, stirring and kneading the water, the flour and the extrusion aid to form a plastic body; (2) sealing and storing the plastic body for a certain time, mixing and kneading the plastic body again, molding the plastic body by adopting a honeycomb molding machine, and carrying out hydrothermal treatment on the molded body under a closed condition; and (3) drying and roasting the product subjected to hydrothermal treatment in the step (2) to obtain the honeycomb carbon-based protective agent filter material. The honeycomb carbon-based filter material disclosed by the inv
