Process using alumina agglomerates to eliminate organic oxygen-containing molecules present in an organic effluent

A process for eliminating organic oxygen-containing molecules present in an organic or gaseous effluent, comprising:

• the steps of adsorbing said organic oxygen-containing molecules onto alumina agglomerates with the following characteristics:
• a specific surface area of 10 m2/g or more;
• a compound selected from the group consisting of alkali metal compounds, alkaline-earth metal compounds and rare earth compounds with a total content by weight of said compounds of 50% or less;
• having a total pore volume of 30 ml/100 g or more if a doping compound is 5000 ppm or more, and their V70 Å is 10 ml/100 g or more, or having a total pore volume of 45 ml/100 g or more if the doping compound is below 5000 ppm.
