Australian subbituminous coal loaded with the single and mixed catalysts of the alkali and transition metal salts [K 2 CO 3 , Ni(NO 3 ) 2 , K 2 SO 4 , Ni(NO 3 ) 2 +K 2 SO 4 ] was gasiยฎed in an internally circulating ยฏuidized bed (0.3 m-I.D. ร 2.7 m-high) with a draft tube (0.1 m-ID ร 0.9 m-high) at
Predictions obtained by using the accepted reaction model together with three different reactor models -plug-flow, complete-mixing and bubble-assemblage -are compared. In general, the three reactor models gave significantly different results. The bubbleassemblage model, therefore, represents a valid
XRD, CaO peaks can be observed in raw char and CaFz peaks can be observed in demineralized char. So, it was clarified that the active species is CaO and the CaF2 cannot act as catalyst during gasification. During acid washing process, CaO reacts with HF product CaFz is the reason of the demineralize
