Resumen:
The interest of this work is to verify that the coffee husk obtained activated carbon by physical and chemical activation with or without phosphoric acid as a binder, the chemically activated carbons produced higher yields, have greater efficiency in absorption. Taking as factors the temperature, the time, the impregnation ratio and the agglutination ratio, and as variables to be studied, the yield and the percentage of activated carbon powder. The produced carbon was studied in the adsorption process with a drink (Pepsi). In this study, the technical feasibility of using coffee residues as a precursor to obtain powdered activated carbon was demonstrated. The best performance values and percentage of powdered activated carbon were obtained in the experimental conditions laboratory level at 500 ºC, 30 min, with a ratio of 1 ml of acid per gram of heavy sample, was placed in an oven at 100 ° C for 24 h. in physical activation 60.62% was obtained in performance while in chemical activation 79.65%. The purpose of this project is to reduce the generation of coffee residues in Yajalón Chiapas and on the other hand that the activated carbon obtained and under laboratory tests can be applied in the future in the industry.
