Soot forms in coal gasification through primary pyrolysis and gas phase reactions. Since soot has lower gasification reactivity, it is important for developing coal gasification technologies to clarify the soot formation mechanism. In this research, the pressure dependency of soot formation behavior was investigated using a pressurized drop tube furnace. Furthermore, the primary pyrolysis, gas phase reactions and char gasification reaction are numerically simulated utilizing the Extended CPD model, detailed chemical reaction mechanism and the random pore model, respectively. As a result, pressure dependency of char formation and gasification behavior was described well by the Extended CPD model and the random pore model. On the other hand, it was suggested that a new soot gasification model is needed to describe the soot formation behavior more precisely under some conditions.
