A process for producing sorbents based on smectites and cellulose-containing materials with a low bulk weight and high absorbency is described; the process is characterized in that a moist mixture of smectite and crushed cellulose-containing primary raw material is treated with intimate shearing action and with subsequent extrusion and is then dried and granulated.

L'invention concerne un procédé de préparation d'agents de sorption à base de bentonites et de matériaux contenant de la cellulose de faible masse volumique apparente et à fort pouvoir absorbant. Ce procédé se caractérise en ce qu'on soumet à un effet de cisaillement intime et qu'on extrude ensuite un mélange de bentonite et de matériaux bruts primaires broyés, contenant de la cellulose, ledit mélange étant enfin séché et granulé.
