Experiment Simulation of Coal Gas Desorption Laws and Main Control Factors Research

We use simulation test device to study different metamorphic degree of coal sample in air medium during coal gas desorption process. Under the condition of different particle size, gas pressure, we simulate gas desorption process of coal samples in air medium, and find out the main factors affecting coal gas desorption process in air medium. We get ideal mathematical expression under the condition of constant pressure during gas desorption process.
