摘要
页岩吸附气和煤层吸附气都是重要的非常规天然气资源。该资源的评价依赖于在不同压力下等温累积吸附量的计算和等温饱和吸附量的确定。不同压力下的等温累积吸附量,需要通过吸附仪的测试资料,利用有关的计算方法求得。基于1976年Adamson(阿达姆森)提出的固相对气相吸附质量的关系式是不确定的,因此,1998年Donohue和Aranovich引用Adamson的吸附关系式,并提出过剩吸附量和绝对吸附量及其关系式也是不正确的。周理等于2000年发表的文章,确认和引用了Donohue和Aranovich过剩吸附量和绝对吸附量及其关系式同样是不正确的。在2015至2018年间,俞凌杰等沿用周理等的过剩吸附量和绝对吸附量关系式,发表了多篇论文。通过本文的研究,认为过剩吸附量和绝对吸附量是两个缺少物理定义和使用价值的伪名词,两者之间的关系式也是不正确的。利用过剩吸附量和绝对吸附量的关系式根本得不到等温吸附量、等温累积吸附量和等温饱和吸附量。
The shale adsorption gas and coalbed adsorption gas are important unconventional natural gas resources.The evaluation of such resources depends on the calculation of the isothermal cumulative adsorption capacity and the determina tion of the isothermal saturated adsorption capacity under different pressures.The isothermal cumulative adsorption capaci ty under different pressures needs to be obtained by the relevant calculation methods based on the test data from the adsorp tion apparatus.Based on the uncertainty of Adamson’s equation of solid-phase adsorption capacity presented in 1976,Donohue and Aranovich cited Adamson’s adsorption equation,and proposed the excess and absolute adsorption capacities and their relational expression that were incorrect in 1998.The excess and absolute adsorption capacities and their relation al expression proposed by Donohue and Aranovich are cited and confirmed in the paper published by ZHOU Li et al.in 2000,which were also incorrect.From 2015 to 2018,YU Lingjie and other relevant experts followed the relational expres sion of the excess adsorption capacity and absolute adsorption capacity proposed by ZHOU Li et al.and published many pa pers in some key Chinese journals.Through the tracking research and comparative analysis in this paper,it is concluded that the excess adsorption capacity and absolute adsorption capacity are two pseudo-words lack of physical definition and use value,and the relational expression of the two is also incorrect.Using the relational expression of the excess adsorption capacity and absolute adsorption capacity,the isothermal adsorption capacity,the isothermal cumulative adsorption capaci ty,and the isothermal saturated adsorption capacity cannot be obtained at all.
