In this environment, biomass is converted to gas and small amounts of residual inert materials. This bed is a significant departure from other gasification technologies that use plasma and extreme temperatures of 1,400 to 1,550 C (2,552 to 2,822 F) to break down biomass. Oxygen and steam are used as fluidizing gases and gasification agents.
