Abstract: A gasification system that comprises a gasification reactor and a synthesis gas cooling vessel, and its use. The gasification reactor comprises a pressure shell for maintaining a pressure higher than atmospheric pressure; a slag bath located in a lower part of the pressure shell; and a gasifier wall arranged inside the pressure shell. The gasifier wall defines a gasification chamber wherein during operation the synthesis gas can be formed, a lower open part of the gasifier wall which is in fluid communication with the slag bath and an open upper end of the gasifier wall which is in fluid communication with the synthesis gas cooling vessel via a connecting conduit. The synthesis gas cooling vessel comprises an inlet for hot synthesis gas; an outlet for cooled synthesis gas; and means to directly contact liquid water with the hot synthesis gas as formed in the gasification reactor in use.

Abstract: A gasification reactor comprising a pressure shell for maintaining a pressure higher than atmospheric pressure; a slag bath located in a lower part of the pressure shell; and a gasifier wall arranged inside the pressure shell, and its use. The gasifier wall defines a gasification chamber wherein during operation a synthesis gas can be formed, a lower open part of the gasifier wall which is in fluid communication with the slag bath and an open upper end of the gasifier wall which is in fluid communication with a quench zone. The quench zone comprises a tubular formed part positioned within the pressure shell, open at its lower and upper end and having a smaller diameter than the pressure shell thereby defining an annular space around the tubular part. The lower open end of the tubular formed part is fluidly connected to the upper end of the gasifier wall and the upper open end of the tubular formed part is in fluid communication with the annular space.

Abstract: A method and system for producing synthesis gas comprising CO, CO2, and H2 from a carbonaceous stream using an oxygen containing stream. A stream containing a carbonaceous material, and a stream containing oxygen are injected into a gasification reactor, where the carbonaceous stream is partially oxidised to obtain a raw synthesis gas. The raw synthesis gas is removed from the gasification reactor and directed into a quenching section wherein a liquid, preferably water, is injected in the form of a mist.
