Abstract

A method of operating a pressurized gasifier (100) includes feeding a carbonaceous material (21) into a pressurized gasification vessel (14) of the gasifier (100) where the gasification vessel is at a pressure P1. Steam (22) as a temperature moderating and gasification agent is fed through a steam ejector (102) into the gasification vessel (14), the steam entering the ejector (102) at a pressure P2 and acting as a motive fluid for the steam ejector (102). Oxygen (24) is also fed into the gasification vessel through the steam ejector (102), the oxygen entering the steam ejector (102) at a pressure P3, where P2 > P1 > P3. The carbonaceous material is gasified in the presence of steam and oxygen at the pressure P1 to produce ash and synthesis gas which includes at least CO and H 2, with ash (23) and synthesis gas (25) being removed from the gasification vessel.
