| description | Disclosed is a method for treating a plastic feedstock, the method including: (a) a dissolution step comprising bringing the feedstock into contact with a dissolution solvent, at a dissolution temperature between 100°C and 300°C and a dissolution pressure of between 1 and 20.0 MPa, the dissolution solvent having a boiling point between -50°c and 250°C, so as to obtain a crude polymer solution; (b) an adsorption step of bringing the crude polymer solution into contact with an absorbent, at a temperature of between 100 and 300°C and a pressure of between 1.0 and 20.0 MPa, so as to obtain a refined polymer solution; then (c) a step of recovering the polymers, so as to obtain at least a solvent fraction and a fraction of purified polymers.
La presente invención se refiere a un proceso para el tratamiento de una carga de plástico, que comprende: a) una etapa de disolución que comprende poner en contacto la carga con un disolvente de disolución, a una temperatura de disolución entre 100 °C y 300 °C y una presión de disolución entre 1 y 20.0 MPa, el disolvente de disolución que tiene una temperatura de ebullición entre -50 °C y 250 °C, para obtener una solución polimérica bruta; b) una etapa de adsorción poniendo en contacto la solución polimérica bruta con un adsorbente, a una temperatura entre 100 y 300 °C y una presión entre 1.0 y 20.0 MPa, para obtener una solución polimérica refinada; después c) una etapa de recuperación de los polímeros, para obtener al menos una fracción del disolvente y una fracción de polímeros purificados. |
