✦ Synopsis

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 demineralized char has a lower reactivity.
