Description

Technical Field

[0001] The utility model relates to the technical field of porous carbon preparation, in particular to a porous carbon preparation activation device. Background Art

[0002] Porous carbon preparation refers to the preparation of carbon materials into pore structures with different sizes, whose pore diameters range from micron-level pores to nano-level ultra-fine pores, with extremely high specific surface areas.

[0003] Porous carbon is usually prepared by physical activation, which uses water vapor, flue gas, air and other oxygen-containing gases or mixed gases as activators, and activates them in contact with carbonized materials at high temperature or activates them alternately with two activators, thereby producing activated carbon products with huge specific surface area and developed pores. When water vapor is used as an activator, the coal gas generated by the activation reaction between it and the carbon material becomes flue gas after combustion, and the flue gas can be reused as an activator, but the existing devices usually discharge it directly, or directly react it with the material without guiding the flow, so that it offsets the flowing gas inside the device, affecting the efficiency of the activation reaction in the device and the rational use of the flue gas.
