Effect of Bulk Density of 1/3 Coking Coal on Pyrolysis Kinetics

Article Preview

Abstract:

This work investigated the weight loss profile and kinetic parameters during the pyrolysis process of the 1/3 coking coal samples from Dongshan (Jixi, Heilongjiang province) in inert gases with the help of thermal-gravimetry apparatus. The characteristic temperatures, the activation energy and the frequency factors gained from the experiment change regularly during the pyrolytic process of the sample coal. The activation energy change with the bulk density indicates that the increase of the bulk density of the coal is beneficial to the coking reaction process of the coking coal.
