Investigation of the Adsorption Process of Biochar Açaí (Euterpea olerácea Mart.) Seeds Produced by Pyrolysis
February 27, 2023
This work aims to investigate the influence of temperature and chemical impregnation in the textural and morphological composition of the bio-adsorbent of bio-adsorption via thermal cracking of the seeds of açaí. The experiments were carried out at 400 °C and 450 °C using a pilot scale reactor. The efficiency of the organic process was calculated in terms of liquid and solid products selected with a chemical impregnation process with NaOH, mainly with the liquid that had a greater product conversion. The elementary samples of the solid products occur with the occurrence of carbonization with an increase in the temperature of the process and the presence of impregnation. The textural and morphological characterization occurred with an analysis of FT-IR, SEM/EDS, XRF, and B.E.T. The in-phase product was developed through the creation of açaí seed in nature and impregnated with NaOH solution (2 M) at temperatures of 400 °C and 450 °C. The adsorption kinetics of acetic acid were investigated at 5, 10, 15, 20, 60, 120, and 180 s. The adsorption is higher at 450 °C and with the chemical impregnation of NaOH since the experiments were able to remove an amount of 317.51 mg acid/g adsorbent acetic acid. All the models analyzed fit the experiments, both for the kinetic models (pseudo-first order and pseudo-second order) and for the equilibrium models (Langmuir and Freundlich).
