Abstract

The desorption behavior of methane in slit was studied in this paper. We build a differential equation which describe dynamic desorption process, and propose a correction method. The mass transfer resistance in free region is considered and the accuracy of the result is improved using this correction method. Based on differential equation, the effects of pressure, temperature and solid material on dynamic desorption speed are analyzed. Desorption becomes faster when pressure increases. When pressure is low, desorption speed increases with increasing temperature; oppositely, desorption speed decreases with increasing temperature. When pressure is low, the desorption speed at different wall material is quartz > kaolinite > graphite; when pressure is high, the desorption speed is quartz > graphite > kaolinite.
