Abstract
Carbon-containing materials are gasified to produce synthesis gas, a mixture of hydrogen and carbon monoxide, in a three zone unified system (oxidizer, reducer and gasifier) using a metal oxide as the oxygen and heat source for the gasification with steam and carbon dioxide. Synthesis gas contacts the metal oxide prior to the gasification to release the oxygen and convert the synthesis gas to steam and carbon dioxide as the gasification medium.
