Abstract
A system and method for cleaning, conditioning, and/or rejuvenating carbon-based sorbents is disclosed where a chemical cleaning process is used to separate contaminants from the sorbent. The contaminants can be disposed of or recycled for industrial uses. The cleaned and/or rejuvenated carbon-based sorbent is recycled back into a reverse venturi shaped fluidized bed apparatus for later use. Spent carbon-based sorbent can be routed for appropriate disposal. The carbon-based sorbents include, but are not limited to, activated carbon sorbent and biochar sorbent. Optionally, the sorbents can be processed through the system prior to exposure to contaminated emissions to enhance and increase the porosity of the outer surface of the sorbents.
