Abstract

Procedure for the production of absorbent substances for the elimination of contaminating liquids scattered on the surface free of water or forming a mixture with it, characterized in that it comprises a phase of feeding by means of mineral substances, such as pumice, obsidians, perlites, vermiculites, and the like., a phase of crushing the food products and classifying them into grain size classes; a phase of oven heat treatment of the insufficiently porous and/or vacuolar starting products, carried out at temperatures ranging from 500ºC to 1,200ºC depending on the nature and density of the starting materials and the degree of porosity and the apparent density you want to obtain, therefore said apparent density being lower than that of water; a phase of contact treatment, carried out in one or more states, by means of a hydrophobizing solution at least and by means of an activating solution of the selectivity or specificity of absorption compared to one or more contaminating organic liquids, said procedure being designed so that in Bypass to the contact treatment phase, a circuit is provided for the preparation of the hydrophobizing solution and for the recovery of the solvent.
