变温变压对 LI 吸附-流动方程的影响
Study on effects of changes of temperature and pressure on LI adsorption-flow equation
摘要
Abstract
LI adsorption-flow equation can be used to measure pressure and temperature effects on coal adsorption capacity.Under isobaric condition, LI adsorption-flow equation's partial differential for temperature ∂V ( )∂T P is smaller than zero, which means that the temperature change has big effect on the adsorption capacity, along with the increase or decrease of the temperature, the adsorption capacity decreases or increases.Under isothermal condition, LI adsorption-flow equation's partial differential for pressure ∂V ( )∂P T is greater than zero, which means that the pressure also affects the coal absorption capability, along with the increase or decrease of the pressure, the adsorption capacity increases or decreases.The total differentiation of LI adsorption-flow equation was done, under the comprehensive effect of temperature and pressure, how temperature and pressure affected the coal absorption capability was researched.Finnaly, the data published in the adsorption capability of coal under integrated influence of temperature and pressure and prediction of content quantity of coal bed gas has been used to verify those arguments.关键词
