Activated carbon after being used in the discoloration of glycerin ceases to be an adsorbent due to its saturation of contaminants due to pigments and traces of fatty acids, for which it is treated as a waste that must be eliminated, inadequate elimination causes problems of Secondary contamination due to the desorption of pollutants by the spent coal. Given this, it is proposed to apply a circular economy when treating this waste, which is the spent coal, to restore its adsorption capacity. That is why in this thesis a chemical regeneration of spent carbon with different concentrations of caustic soda NaOH(l) solutions is proposed, having as optimal regeneration values a caustic soda dilution concentration of 11M with agitation of 100 rpm for a time of 1h at room temperature since in a water bath at 80°C in the regeneration a significant improvement is not seen, in addition the drainage of the excess of caustic soda will be sent to the neutralization process of the acidified glycerol for the glycerol distillation process In this way, the liquid residue that is generated in this chemical regeneration is reused, it is necessary that the regenerated carbon be washed until the pH is between 7 and 8 and the filtrate water is transparent colorless, in addition to drying it at 105 ° C for two hours the regenerated carbon will remain partially hydrated because the water content will be extracted in the vacuum dehydration process. It was obtained that its adsorption capacity was 931.286 mI2/g index for small molecules and its adsorption capacity for small molecules is 21.58 gAM/100g, these values being close to the values of new activated carbon according to its quality certificate 980.41 mgI2/ g and 24.96 gAM/100g.
