Steam gasification of AD coal was conducted using a circulating dual bubbling fluidized bed (CDBFB) system in this study. The CDBFB consisted of two bubbling fluidized beds, with one serving as a gasifier and the other as a combustor. Two kinds of bed materials (porous γ-alumina particle and non-porous silica sand) were used in the CDBFB system. Carbon yield in product gas in case of alumina was larger than that of silica sand case, because almost all the tar was captured and reformed on the alumina. Furthermore, minimum fraction of carbon combusted to maintain autothermal condition in the CDBFB experiment was predicted by a system simulation considering heat and material flow in the dual bed reactor.
