Investigation of the Adsorption Process of Biochar Açaí (Euterpea olerácea Mart.) Seeds Produced by Pyrolysis

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