SUMMARY:

Given the current context of excessive generation of industrial waste, the compound phenol has been attracting attention due to the high concentration found and the severity of its damage both in environmental aspects and to human and animal health. This compound is found in different types of waste and mainly in effluents discarded by industries (petroleum, petrochemical and pharmaceutical), with emphasis on its presence in produced water generated on a large scale in the production and extraction of petroleum and its derivatives. In this context, commercial activated carbon WV1050 will be used as an adsorbent, due to its important characteristics such as high surface area (1674m²/g) and high total pore volume (1.10 cm³/g), which makes it a promising material in the treatment of effluents with phenolic compounds. In this study, synthetic solutions produced from phenol will be evaluated by the batch and fixed bed adsorption process, to obtain a database and, therefore, be used and compared in simulation and mathematical modeling. First, initial tests will be carried out by varying the mass of the adsorbent. To characterize the carbon, the techniques of SEM, XRD, FTIR and BET will be used before and after the adsorption process of the phenol compound. An experimental design will be produced with the variables that have the greatest influence on the process, which will later be used in the kinetic study to be developed, aiming to evaluate whether the experimental data fit the pseudo 1st and 2nd order models as well as the Morris and Weber model. For the batch process, adsorption isotherms will be constructed and evaluated to see if they fit the Langmuir and/or Freundlich models. The effects of temperature from 25 to 55ºC will be studied to evaluate the thermodynamic feasibility of phenol adsorption. In this study, the values of Gibbs free energy (ΔG°), entropy (ΔH°) and enthalpy (ΔS°) of the process will be determined. Finally, in the dynamic bed study, breakthrough curves will be constructed to evaluate the adsorption capacity and bed performance.
