Zusammenfassung:	The present description is related to the field of hydrocarbon production by gasification of carbonaceous material. More specifically it discloses a method for naphthalene removal from a gas using a solid adsorbent material comprising benzene for the removal. The removal can be applied to e.g. crude syngas main stream and/or carbon dioxide exhaust side stream. Preferably the adsorption to the adsorbent material is reversible so that the material can be reused and naphthalene and possibly benzene recovered after regeneration. La présente invention concerne le domaine de la production d'hydrocarbures par gazéification de matière carbonée. Plus précisément l'invention porte sur un procédé pour l'élimination de naphtalène d'un gaz à l'aide d'un matériau adsorbant solide comprenant du benzène pour l'élimination. L'élimination peut être appliquée par exemple à un courant principal de gaz de synthèse brut et/ou un courant secondaire d'évacuation de dioxyde de carbone. De préférence l'adsorption sur le matériau adsorbant est réversible de façon à pouvoir réutiliser le matériau et récupérer le naphtalène et éventuellement le benzène après régénération.
