Abstract EN
Shale gas is an effective gas resource all over the world.
The evaluation of pore structure plays a critical role in exploring shale gas efficiently.
Nitrogen adsorption experiment is one of the significant approaches to analyze pore size structure of shale.
Shale is extremely heterogeneous due to component diversity and structure complexity.
Therefore, adsorption isotherms for homogeneous adsorbents and empirical isotherms may not apply to shale.
The shape of adsorption-desorption curve indicates that nitrogen adsorption on shale includes monolayer adsorption, multilayer adsorption, and capillary condensation.
Usually, Langmuir isotherm is a monolayer adsorption model for ideal interfaces; BET (Brunauer, Emmett, Teller) adsorption isotherm is a multilayer adsorption model based on specific assumptions; Freundlich isotherm is an empirical equation widely applied in liquid phase adsorption.
In this study, a new nitrogen adsorption isotherm is applied to simultaneously depict monolayer adsorption, multilayer adsorption, and capillary condensation, which provides more real and accurate representation of nitrogen adsorption on shale.
In addition, parameters are discussed in relation to heat of adsorption which is relevant to the shape of the adsorption isotherm curve.
The curve fitting results indicate that our new nitrogen adsorption isotherm can appropriately describe the whole process of nitrogen adsorption on shale.
