Introduction

The tester can detect the adsorption law of coal on the basis of the isothermal adsorption test under the condition of the simulated coal reservoir conditions, including temperature, pressure, water content, combination gas, maceral and coal grain grade, and then measure the Langmuir pressure and volume and other test parameters. During the experiments the following can be finished: (1) obtain critical desorption pressure, saturation degree, recoverable coefficient and so on; (2) predict the development performance of coal reservoir; (3) evaluate bed productivity and recovery ratio. The tester has the characteristics of rational structure, high automation degree and its pressure and temperature are controlled by high precision sensors. In addition, it has functions of rapid data acquisition, data process and chart plotting.
