Experimental Study on the Micro-Structure of the Coal Char at High Heating Rate and Elevated Pressures

Abstract:

In the process of pressurized coal gasification, coal particles experience rapid devolatilization to become chars, which react with H₂O and CO₂. The characteristics of the char play an important role in the gasification research. Hence acquisition of coal char fitting real situation is demanded. The article uses PDTF system to produce coal char at high heating rate under pressurized conditions, and char morphology and pore structure are analyzed.
