变温过程瓦斯解吸量变化规律研究
Study on Change Law of Gas Desorption Amount During Temperature-changing Process
摘要
Abstract
In order to simulate the gas desorption characteristics in the process of low temperature coring,and to provide theoretical reference for low temperature coring,choosing coal samples in Shanxi Liulin Xingwu Coal Mine,depending on low temperature coring simulation device,we adopt dry ice as refrigerant to carry on a certain heating power to change temperature desorption.The experimental results show that the change of desorption quantity is divided into three stages:the early increase stage,the middle steady stage and the later increase stage.Under a certain heating power,with the increase of adsorption equilibrium pressure,the gas desorption capacity increases in the early stage and the later stage,and the middle stability phase has a tendency of shortening.The gas desorption amount below a certain temperature is larger with the increasing of adsorption equilibrium pressure.关键词
