The present invention relates to a method of producing synthesis gas comprising CO, CO2 , and H2 from a carbonaceous stream (3) using an oxygen containing stream (4) , the method comprising at least the steps of : (a) injecting a carbonaceous stream (3) and an oxygen containing stream (4) into a gasification reactor (2) ; (b) at least partially oxidising the carbonaceous stream (3) in the gasification reactor (2) , thereby- obtaining a raw synthesis gas; (c) removing the raw synthesis gas obtained in step (b) from the gasification reactor (2) into a quenching section ( 6) ; and (d) injecting a liquid (17) , preferably water, into the quenching section (2) in the form of a mist. In a further aspect the present invention relates to a system (1) for performing the method.

L'invention concerne un procédé de production de gaz synthétique renfermant CO, CO2 et H2 à partir d'un flux carboné (3) au moyen d'un flux contenant de l'oxygène (4), le procédé consiste à (a) injecter un flux carboné (3) et un flux contenant de l'oxygène (4) dans un réacteur de gazéification (2) ; (b) à oxyder au moins en partie le flux carboné (3) dans le réacteur de gazéification (2), de manière à obtenir un gaz synthétique brut ; (c) à éliminer le gaz synthétique brut obtenu à l'étape (b), du réacteur de gazéification (2) pour l'acheminer dans une section de trempe (6) ; et (d) à injecter un liquide (17), de préférence de l'eau, dans la section de trempe (2) sous la forme d'un brouillard. Un autre aspect de l'invention concerne un système (1) permettant d'exécuter ledit procédé.
