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.

The pyrolysis tests of Shenhua coal and Shenhua direct liquefaction residue have been carried out using thermogravimetric at the differential heating rate. The kinetic parameters k and E were calculated using DAEM method. Results show DAME model can describe the pyrolysis behavior of Shenhua coal within the range of 20% to 95%, the activation energy of coal pyrolysis ranges from 53.98 to 279.38 kJ/mol, and DAME model can describe the behavior of Shenhua direct liquefaction residue within the range of 10% to 80%, the activation energy of residue pyrolysis is about 170 kJ/mol. The results of which are basically consistent with the experimental data.
