在这项研究中，我们报告了一种新的有效的污泥消化气（沼气）吸附储存技术。测量了沼气主要成分甲烷和二氧化碳在 273-333 K 温度范围和 6 MPa 压力下在五种活性炭上的纯吸附平衡和二元吸附平衡的实验数据。 Toth 和扩展 Toth 模型均符合纯等温线。使用基于扩展托斯模型的理想吸附溶液理论（IAST）预测二元平衡，并预测实验数据。计算纯吸附和二元吸附的差焓，并使用沼气组合物中混合气体的绝热和等压线来估计考虑到增加的活性炭温度的二元气体、甲烷和二氧化碳的存储密度。
In this study, we report a new effective sludge-digestion gas (biogas) adsorption storage technology. The experimental data of the pure and binary adsorption equilibrium of methane and carbon dioxide, which are the main components of the biogas, on five types of activated carbons at a temperature range of 273–333 K and pressures up to 6 MPa, were measured. Pure isotherms were fitted with the Toth and extended Toth models. Binary equilibrium was predicted using the Ideal Adsorbed Solution Theory (IAST) based on the extended Toth model with the experimental data being predicted as well. The differential enthalpy of the pure and binary adsorption was calculated, and storage densities of the binary gases, methane and carbon dioxide, considering the increased activated carbon temperature, were estimated using the adiabat and isobar of mixed gases in the biogas composition.
