Title (EN) METHOD FOR PREPARING A HYDROCARBON COMPOSITION
(FR) PROCEDE DE FABRICATION D'UNE COMPOSITION HYDROCARBONEE
Abstract:
(EN) The present invention relates to a method for preparing a hydrocarbon composition including the following steps: (i) producing a mixture of granulates with a maximum diameter of less than or equal to 30mm and in a quantity of less than or equal to 0.8g per square meter of specific surface developed by the granulates of at least one liquid cationic polymer laden with cations at a density greater than or equal to 0.5 meq/g and an intrinsic viscosity of 0.01 to 0.8 dl/g; and (ii) contacting the mixture produced in step (i) with at least one hydrocarbon binder. A hydrocarbon composition including at least one specific cationic polymer and the use of at least one specific cationic polymer for the surface treatment of granulates for preparing a hydrocarbon composition are the other two aims of the present invention.
(FR) La présente invention a pour objet un procédé de fabrication d'une composition hydrocarbonée comprenant les étapes suivantes : (i) réaliser un mélange de granulats de diamètre maximal inférieur ou égal à 30 mm et d'une quantité inférieure ou égale à 0,8 g par mètre carré de surface spécifique développée par les granulats d'au moins un polymère cationique sous forme liquide ayant une densité de charges cationiques supérieure ou égale à 0,5 meq/g et une viscosité intrinsèque comprise de 0,01 à 0,8 dl/g; et (ii) mettre en contact le mélange obtenu à l'étape (i) avec au moins un liant hydrocarboné. Une composition hydrocarbonée comprenant au moins un polymère cationique spécifique et l'utilisation d'au moins un polymère cationique spécifique pour le traitement de surface de granulats destinés à la préparation d'une composition hydrocarbonée sont les deux autres objets de la présente invention.
