Abstract:
1. A method of producing synthesis gas comprising CO, CO 2 , and H 2 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 μm, 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.
