Pyrolysis Kinetic

The pyrolysis characteristics of Jianfanggou(JFG) coal was studied using a thermo-gravimetric analyzer and the pyrolysis kinetic parameters were calculated at the different heating rate. The results showed the DTG curves under different heating rate had three peaks and the corresponding temperature were 100°C, 470°C and 750°C, the pyrolysis process can be divided into three stages conclusively. The maximum weight loss rate at 470°C indicated the major weight loss occurred in the second stage. The Tb, Tf and T∞ obtained under experiment situation. The results of the JFG coal pyrolysis kinetic showed the Tb, Tf and T∞ increased gradually with the accretion of the heating rate. In the meantime, the variation of frequency factor was consistent with the trend of activation energy.

In this paper,a research was carried out on the regularities of carbonization temperature,holding time and mass on weightlessness of low rank coal. The experiment showed experiments in a certern range (450°C~700°C,<60min),weightlessness of coal in an increasing trend,the remained volatile content of semi-coke was measured reduce tending to value,ash content increased,fixed carbon gradually increased in the temperature range with the improvement of the carbonization temperature and holding time,also hydrogen and oxygen content of the char decreased,a significant increased in the carbon content,nitrogen and sulfur content was essentially the same. Reactivity of CO2 and semi-coke obtained in different carbonization conditions were better,the response rates are 100% when the temperature exceeded 1000°C. Best condition of dry distillation: carbonization temperature was 500°C~650°C,mass of low rank coal was less than 30g,holding time was between 30 minutes to 40 minutes.
