MILD CATALYTIC STEAM GASIFICATION PROCESS

摘要

The present invention provides an improved alkali metal catalyzed steam gasification process that utilizes a CO2 trap material and/or a mineral binder material within the gasifier. The process optimally achieves over 90% carbon conversion with over 80% yield of methane. The raw gas product can be used directly as fuel. The catalyst can be recovered from the solid purge and recycled to the gasifier and/or the CO2 trap can be regenerated and recycled to the gasifier.
