Abstract
The invention discloses a method for preparing high thermal conductivity active carbon taking waste cotton cloth as a raw material. The method comprises the following steps: placing waste cotton pieces into a zinc chloride solution to soak, distilling under reduced pressure, then drying, adding 5-40 wt% of expanded graphite, mixing fully, firing and activating in the presence of nitrogen at 300-500 DEG C for 0.5-2 h, stopping heating, cooling to room temperature in the presence of nitrogen, washing with deionized water to neutral, and drying. In the present invention, waste cotton cloth is used as the raw material for the production of activated carbon, thereby achieving to control pollution with waste and expand production raw material sources of activated carbon. The activated carbon prepared by the invention is high in thermal conductivity, can be efficiently recycled, can keep good adsorption properties after multiple regenerations, and helps to expand industrial application field and scope of activated carbon.
