Abstract

New adsorbents of mineral origin which are selective for non-polar compounds, process for their preparation and applications The new adsorbents comprise an adsorbent mineral treated with a water-repellent substance in a proportion of between 2 and 11% by weight based on the adsorbent. The process comprises: (a) mixing the water-repellent substance previously diluted in a solvent with the adsorbent and removing the solvent by heat treatment, or (b) applying the water-repellent substance directly to the adsorbent followed by heat treatment, or (c) immersing the adsorbent in an emulsion of the water repellent substance in water, removing the adsorbent and subjecting it to heat treatment to dry it. Application in the selective separation of hydrocarbons which are dispersed or present in masses of water, for example the elimination of "black tides", the containment and cleaning up of spills, contaminated effluent purifier beds, etc.
