Title
(EN) PRODUCTION AND ISOLATION OF MONOCYCLIC AROMATIC COMPOUNDS FROM A GASIFICATION GAS
(FR) PRODUCTION ET ISOLEMENT DE COMPOSÉS AROMATIQUES MONOCYCLIQUES À PARTIR D'UN GAZ DE GAZÉIFICATION
Abstract
(EN)
The present invention concerns a process and system for producing and isolating a fraction of monocyclic aromatic compounds from a gasification gas. The process comprises (a) contacting the gas with a catalyst capable of converting ethylene and possibly other unsaturated hydrocarbons into monocyclic aromatic compounds; and (b) isolating monocyclic aromatic compounds from the gas originating from step (a). The present invention is ideally suited for treatment of gas from coal, biomass or waste gasification, which comprises substantial amounts of ethylene as well as monocyclic aromatic compounds. Treatment according to the invention first converts the ethylene into further monocyclic aromatic compounds, and the entire fraction of monocyclic aromatic compounds is isolated to obtain a valuable product.

La présente invention concerne un procédé et un système de production et d'isolement d'une fraction de composés aromatiques monocycliques à partir d'un gaz de gazéification. Le procédé comprend (a) la mise en contact du gaz avec un catalyseur en mesure de convertir l'éthylène et éventuellement d'autres hydrocarbures insaturés en composés aromatiques monocycliques; et (b) l'isolement de composés aromatiques monocycliques à partir du gaz provenant de l'étape (a). La présente invention est idéalement appropriée pour le traitement de gaz provenant de charbon, de biomasse ou de gazéification de déchets, qui comprend des quantités importantes d'éthylène ainsi que des composés aromatiques monocycliques. Le traitement selon l'invention convertit d'abord l'éthylène en d'autres composés aromatiques monocycliques et la fraction entière de composés aromatiques monocycliques est isolée pour obtenir un produit de valeur.
