结合氦孔隙度仪以及化工和煤岩气体吸附测试仪的测试方法和原理 ,研制了一种改进的固体介质气体吸附测量仪器。该仪器能在较大的温度 (15℃～ 15 0℃ )、压力 (0～ 6 0MPa)范围内 ,精确测量固结态圆柱状的、具有不同孔隙度、渗透率 (不限 )和非均质特征的岩心样品的气体 (各类纯组份气体或混合气体 )吸 /脱附等温线 ,并具有流程简洁、操作方便、性能可靠、制作成本低廉等优点。
Combined with the helium porosimeter and the testing methods and principles of chemical and coal-rock gas adsorption tester, an improved solid-medium gas adsorption measuring instrument was developed. The instrument can accurately measure the solidified cylindrical shape with different porosity, permeability (not limited) and non-uniform (non-uniform) in the range of larger temperature (15 ℃ ~ 150 ℃) and pressure Quality characteristics of the core sample gas (all kinds of pure gas or mixed gas) adsorption / desorption isotherms, and has a simple process, easy operation, reliable performance, low production costs and so on.
