The pyrolysis of cornstalk was studied by using Pyris-ITGA thermogravimetric apparatus with the heating rates of 20, 40, 60, 80, 100K/min and final temperature of 1073 K. Through the analysis of TG and DTG, the results show that the pyrolysis process of cornstalk includes four steps: drying, pre-pyrolysis, mainpyrolysis and carbonization; As the heating rate increased, both the maximum pyrolysis rate...
Pyrolysis process of dead beer yeast powder was studied through thermogravimetric analyzer. Cu2+ adsorption mechanism was analysed by SEM and FTIR. The results showed: in thermogravimetric test, TG and DTG figures indicated five pyrolytic stages, weight losting in the third(247degC- 309degC) and fourth(309degC-420degC) stages, most important stages, accounted for 68.3% of total weight losting and...
The pyrolysis of rubber from the sidewall and tread of a passenger car tire was carried out in a nitrogen flow at a wide range of final temperatures. Derivative thermogravimetric analysis (DTG) was applied to examine the kinetics at the different process conditions of completed pyrolysis. Two characteristic stages were observed in the DTG curves. The first stage corresponded to the decomposition of...
The investigation of europium(III) sulphate hydrate and samarium(III) sulphate hydrate was performed by thermal analysis (TG-DTG) and simultaneous infrared evolved gas analysis-Fourier transformed infrared (EGA-FTIR) spectroscopy. The TG, DTG and DTA curves were recorded at the 25–1400°C in the dynamic air atmosphere by TG/DTA analyser. The infrared evolved gas analysis was obtained on the FTIR spectrometer...
