The present invention relates to a method for removing oxygen-containing organic molecules such as alcohols and organic acids present in organic effluents or gas effluents. The removal of the method is characterized by being carried out by adsorption on an alumina agglomerate having the following characteristics.n n n A specific surface area of 10 m 2 / g or more, preferably 30 m 2 / g or more;n n n Alkali metal compounds, alkaline earth metal compounds having a total weight content between 50% or less, preferably 25% or less, more preferably 5000 ppm to 20%, even more preferably 5000 ppm to 12% And optionally containing one or more doping compounds selected from rare earth compounds;n n n If the dopant content is 5000 ppm or more, the total pore volume is 30 ml / 100 g or more, more preferably 35 ml / 100 g or more, and V 70Å is 10 ml / 100 g or more, preferably 15 ml / 100g or more, more preferably 22 ml / 100g or more, even more preferably 28 ml / 100g or more, and optimally 35 ml / 100g or more;n n n When the dopant content is less than 5000 ppm, the total pore volume is 45 ml / 100 g or more, preferably 50 ml / 100 g or more, more preferably 55 ml / 100 g or more, and V 70Å is 15 Ml / 100g or more, preferably 22 ml / 100g or more, more preferably 28 ml / 100g or more, and optimally 35 ml / 100g or more. |
