Abstract: In order to study coal granule adsorption/desorption characteristics under the condition of infrared, we use self-developed adsorption/desorption device under conditions of infrared; through the granular coal desorption experiments under the conditions of different infrared temperature and comparing the granular coal desorption experiments under the condition of infrared and water bath, combination of different adsorption/desorption equation is carried out fitting analysis of the experimental data. Results show that the infrared can promote particle coal desorption, increase the desorption rate, increase the desorption amount; under the condition of the same adsorption, under the conditions of the infrared the total desorption is 1.3 to 1.4 times under the action of water bath; under the action of the infrared coal particles desorption conform to the upper limit monotonically increasing function, and Wang You'an equation can be a very good description of desorption characteristics.
