煤层气解吸的温度效应
Mechanism of coalbed methane desorption at different temperatures
摘要
Abstract
In order to investigate the influence of temperature on CBM desorptoin effect, by using adsorption and desorption experiment of coal seam 3 in Sihe mine at 6 temperatures, the adsorption and desorption formula of the coal seam was obtained, and isosteric adsorbed heat was calculated.It is considered in the analysis that the saturated adsorption amount decreased with the increased temperature of CBM reservoir; the main reason for delayed desorption process compared with adsorption was the action of non-physical adsorption constant C.The value C increased with increased temperature of reservoir; fall-off desorption was associated with heat adsorption (temperature drop) and in the same time hindered continuous desorpfion process.It is practical theoretically to accelerate desorption process by increasing temperature which should be taken into account in engineering application.关键词
