Abstract

A method of producing synthesis gas by introducing a feed material to be gasified into a gasification apparatus comprising at least one fluidized component operable as a fluidized bed, wherein the gasification apparatus is configured to convert at least a portion of the feed material into a gasifier product gas comprising synthesis gas; and maintaining fluidization of the at least one fluidized component by introducing a fluidization gas thereto, wherein the fluidization gas comprises at least one component other than steam. A system for producing synthesis gas is also provided.
