A PROCEDURE FOR THE REGENERATION OF SPENT ACTIVE CARBON IMPREGNATED WITH CAUSTIC.

摘要

An improved process for the regeneration of activated carbon impregnated with caustic is described. A two stage wash with caustic solutions of about 50 percent and about 15 percent removes both organic and sulfur contaminants. This regeneration returns the carbon essentially to its original capacity for adsorption of malodorous compounds.
