Indonesian sub-bituminous coal was gasified with steam in a circulating fluidized bed (CFB) developed here. The CFB consisted of three bubbling fluidized beds, with serving as a pyrolyzer, a gasifier, and a combustor. In the CFB system, pyrolysis was terminated in the pyrolyzer and then the resultant char was gasified with steam in the gasifier, indicating that inhibition of char gasification by the volatiles formed by devolatilization can be avoided. We confirmed that carbon yield in product gas in the CFB system was enhanced by the isolation of pyrolyzer from the gasifier.
