Title: | Spent active carbon regeneration by wetting with sodium hydroxide soln., extn. of organic load with methanol, methanol recovery and washing | Other Titles: | Procedeu de regenerare a carbunilor activi epuizati | Authors: | Cruceru, Mihail Nicolau, Margareta Ballo, Aureliea Cosma, Cristiana |
Keywords: | Active carbon;Regeneration | Issue Date: | 30-May-1986 | Abstract: | The spent C is wetted with an alkaline 1 0% NaOH soln. for 1 0 min. The organic load is extd. with MeOH, at reflux, for 30 min. The MeOH, contg. organic substances and alkaline soln., is recovered by distn. and recycled to the regeneration process. After removing the residual MeOH with steam, the regenerated C is washed with a soln. of 4% Na metabisulphite to pH 1 .5. Washing is continued with a soln. of 0.001 % Na metabisulphite, until the washing water reaches pH 4.5. |
