1. A method of producing synthesis gas comprising CO, CO2, and H2 from a carbonaceous stream using an oxygen containing stream, the method comprising the steps of:
- (a) injecting a carbonaceous stream and an oxygen containing stream into a gasification reactor;
(b) at least partially oxidizing the carbonaceous stream in the gasification reactor, thereby obtaining a raw synthesis gas;
(c) removing the raw synthesis gas obtained in step (b) from an outlet at a top of the gasification reactor into a quenching section located above the gasification reactor; and
(d) injecting liquid water into the quenching section in a direction away from the gasification reactor in the form of a mist comprising droplets having a diameter within a range from about 50 to about 200 μ
m, wherein the water has a temperature of above 150°
C., and wherein the water has a temperature of at most 50°
C. below a bubble point of the liquid at the pressure of the raw synthesis gas.

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 oxidized 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.
