Abstract[English]
A broad aspect of the present disclosure relates to a process for conversion of a feed-stock containing at least 5 wt% aromatics, originating from thermal decomposition of solids, comprising the steps of directing the feedstock to contact a material catalytically active in hydrodeoxygenation under hydrodeoxygenation conditions in the presence of dihydrogen, to provide a deoxygenated intermediate, directing at least an amount of the deoxygenated intermediate to contact a material catalytically active in hydrodearomatization under hydrodearomatization conditions in the presence of dihydrogen, to provide an dearomatized intermediate.This has the associated benefit of converting a feedstock such as pyrolysis oil to a product or an intermediate compatible with diesel fuel requirements with a minimal yield loss.[French]
D'une façon large, la présente invention concerne un procédé pour la conversion d'une charge d'alimentation contenant au moins 5 % en poids de composés aromatiques, provenant de la décomposition thermique de matières solides, comprenant les étapes consistant à mettre la charge d'alimentation en contact avec un matériau catalytiquement actif en hydrodésoxygénation dans des conditions d'hydrodésoxygénation en présence de dihydrogène, pour fournir un intermédiaire désoxygéné, et mettre au moins une certaine quantité de l'intermédiaire désoxygéné en contact avec un matériau catalytiquement actif en hydrodésaromatisation dans des conditions d'hydrodésaromatisation en présence de dihydrogène, pour obtenir un intermédiaire désaromatisé. Ceci a l'avantage associé de convertir une charge d'alimentation telle que de l'huile de pyrolyse en un produit ou un intermédiaire compatible avec les exigences de carburant diesel avec une perte minimale de rendement.
