| titleOfInvention | Preparation method for asphalt-based spherical activated carbon which requires no infusibilization process |
| abstract | The present invention is a preparation method for asphalt-based spherical activated carbon which requires no infusibilization process. Placing coal tar asphalt into a melting device; introducing compressed air of 0.1 MPa-0.5 MPa into the device and stirring until a melting temperature of 280° C.-350° C. is reached; continuing for 2-8 hours until the base material has a softening point of 200° C.-260° C.; after cooling down, pulverizing the base material to obtain asphalt powder. Obtaining 34%-79% by mass of carbon powder, 1%-10% by mass of binder, and 20%-65% by mass of the asphalt powder and then forming spherical particles with a diameter of 0.5 mm-5 mm with the carbon powder, the binder and the asphalt powder at room temperature. Introducing the spherical particles of asphalt directly into an asphalt carbonization furnace for carbonization at a temperature of 600° C.-900° C. under protection of an inert gas to obtain asphalt spherical carbon. Asphalt spherical carbon is subject to activation treatment to obtain asphalt spherical activated carbon. The preparation method of the present invention reduces processing difficulty and production costs significantly. |
