The invention concerns a method for treating viscous hydrocarbon containing asphaltenes, which consists in performing the following steps: precipitating at least part of the asphaltenes by adding into the hydrocarbon an appropriate solvent; adding into the hydrocarbon polymerization products adapted to encapsulate the precipitated asphaltenes to inert same.
La présente invention concerne une méthode de traitement d'un hydrocarbure visqueux contenant des asphaltènes, dans laquelle on effectue les étapes suivantes: on précipite au moins une partie des asphaltènes par l'ajout dans l'hydrocarbure d'un solvant approprié ; on ajoute dans l'hydrocarbure des produits de polymérisation adaptés à encapsuler les asphaltènes précipités de façon à les inerter.
