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.

Abstract.Based on TG-DTG-DTA, combustion characteristics and kinetic parameters of impure coal in the 10 °C / min heating rate were studied. The results showed that with the increase in the proportion of impurities, ignition temperature, burned temperature significantly improved; combustion characteristics of index clearly decreased; combustion process can be described by a diffusion kinetic equation

Final volatiles yield of biomass devolatization at flash heating rate was determined via experiments. Samples of wheat straw and corn stalk powder were dispersed in the feeder and were carried by argon into the laminar entrained flow reactor. Flash devolatization of tiny biomass particles was accomplished in the moderate temperature reactor. Residue was collected and the ash content of it was detected in a thermo-grametric analyzer. Final volatiles yield was calculated using ash trace method. Altogether, 96 experiments (including repeat ones) of different reaction temperature (500, 550, 600, 650 °C), different collecting distance (550, 600, 650, 700 mm away from inlet). Results showed that final volatiles yields of wheat straw and corn stalk are 79%, 85 % separately. High reproducibility of the experiments showed it is a reliable method to determine final volatiles yield of biomass devolatization at flash heating rate. Kinetic parameters for wheat straw and corn stalk were modified as A=1009/s, E=3782kJ/mol and A=596/s, E=3716kJ/mol, respectively.
