The biodiesel is a renewable and clean source of energy and its use as an alternative fuel from oil has been increasing. Consequently, the production of crude glycerol, a byproduct of the transesterification reaction for biodiesel production, is increasing. Due to the growth in the supply of crude glycerol in the market, new methods of purification are necessary in order to rise its market value. Therefore, this paper aim to study the purification of crude glycerol by means of adsorption to add value to this byproduct. The speedy of agitation was tested for the rotations of 50, 100, 150, 200 and 235 rpm. The adsorption kinetics in times of 1, 5, 10, 20, 30, 60, 90, 120, 180, 240 and 300 minutes and the adsorption isotherms with different activated carbon concentration (5, 10, 30, 50, 70, 100, 150 and 200 g L-1) were made. The adsorption results indicated that the activated carbon from pinewood is effective in the purification process removing, therefore, 99,0% of color and impurities from the crude glycerol.
