53.石炭水蒸気ガス化における炭素構造変化・灰分挙動とガス化速度との相関(2) : 水蒸気ガス化はどのように進行しているか

抄録

We investigated steam gasification of coal char and examined the structural change of carbon and ash. From LRS (Laser Raman Spectra)-mapping, BET surface area, XRD, SEM/EDX elemental mapping, we found that the gasification of coal char was strongly affected by the ash behavior and coal structural change. So we clarify the mechanism of the gasification of coal char from these viewpoints.
