Abstract

La présente invention concerne un système de fabrication comprenant une source de dioxyde de carbone utilisable pour distribuer un flux primaire de dioxyde de carbone, une source de chaleur sans combustion qui fonctionne pour chauffer le flux primaire de dioxyde de carbone, et un dispositif de chauffage ayant une extrémité d'entrée et une extrémité de sortie, l'extrémité de sortie étant positionnée pour recevoir le flux primaire de dioxyde de carbone provenant de la source de chaleur sans combustion. Un écoulement de matière première entre dans le réacteur au niveau de l'extrémité d'entrée et un écoulement de produit fini sort du réacteur au niveau de l'extrémité de sortie, le réacteur coopérant avec le flux primaire de dioxyde de carbone pour convertir l'écoulement de matière première en l'écoulement de produit fini. Une enceinte est agencée pour capturer du dioxyde de carbone à partir de la source de chaleur sans combustion et du dispositif de chauffage, et pour diriger le dioxyde de carbone capturé vers la source de dioxyde de carbone.
