Abstract

The invention relates to an activated carbon recovery processing technology and belongs to the field of activated carbon processing. An internal boiling activated carbon treatment process, the activated carbon is soaked in an alcohol-water solution; then the soaked activated carbon is heated in microwave radiation; finally, the activated carbon is dried in a vacuum system to obtain a recovered activated carbon product. The process uses the activated carbon internal boiling process, under the action of microwaves, combined with the control of air pressure, to regulate the internal boiling of the solution in the internal voids of the activated carbon, and promote the efficient discharge of harmful substances adsorbed inside the activated carbon. After testing, the specific surface area of ​​activated carbon prepared by this process reaches more than 99.5% of that of the original activated carbon, and the adsorption capacity is almost the same as that of the original activated carbon.

Description

technical field

[0001] The invention relates to a secondary processing technology of activated carbon, in particular to an inner boiling activated carbon processing technology. Background technique

[0002] Activated carbon is a black porous solid carbon. The main component of activated carbon is carbon, which is irregularly arranged in structure, with pores between cross-connections, which will produce carbon tissue defects during activation, low bulk density, large specific surface area, and strong adsorption performance, which is extremely versatile. A kind of industrial adsorbent, the specific surface area of ​​ordinary activated carbon is 500 ~ 1700m 2 / g.

[0003] Activated carbon is a hydrophobic adsorbent made of carbon-based substances as raw materials through high-temperature carbonization and activation. Activated carbon contains a large number of micropores and has a huge specific surface area, which can effectively remove pigments and odors, and can remove mo...
