In this work, the potential of two-dimensional equations of state (2D) was explored in terms of high pressure adsorption prediction and parametric analysis. To attain this objective, firstly, low pressure experimental data for CO₂ and CH₄ adsorption on NaY zeolite and babassu activated carbon were correlated with two-dimensional equations of state of van der Waals (2D vdW), Peng-Robinson (2D PR), Zhou et al. (2D ZGR) and 2D ZGRm ($m$ as a fitted paramter). Then, high pressure isotherms were predicted for the same systems and compared to experimental data. Thus, a parametric analysis was made varying 2D ZGRm parameters: adsorbate-adsorbate interaction ($a_2$); co-area ($b_2$); Henry's Law constant ($K$); heterogeneity parameter ($m$); adsorbent specific area ($A$). Results indicate that these parameters present a critical value at a given pressure that separates homogeneous and heterogeneous adsorbed phases. Depending on the set of parameters applied, different types of isotherms can be described by 2D ZGRm. Therefore, it was verified that 2D EOS have the potential to be applied for both low pressure characterization of adsorbent materials and high-pressure adsorption processes.

在这项工作中，从高压吸附预测和参数分析的角度探讨了二维状态方程（2D）的潜力。为了达到这个目的，首先，将NaY沸石和Babassu活性炭上的CO ₂和CH ₄吸附的低压实验数据与范德华（2D vdW），Peng-Robinson（2D PR）的二维状态方程相关联。 ，Zhou等。（2D ZGR）和2D ZGR m（$米$作为合适的参数）。然后，预测了相同系统的高压等温线，并将其与实验数据进行了比较。因此，对2D ZGR m参数进行了参数分析：吸附物-吸附物相互作用（${\mathrm{一个}}_{\mathrm{2个}}$）; 共同区域（$b_{\mathrm{2个}}$）; 亨利定律常数（$ķ$）; 异质性参数（$米$）; 吸附剂比表面积（$\mathrm{一个}$）。结果表明，这些参数在给定压力下呈现出临界值，该临界值将均相和非均相吸附相分离。根据所应用的参数集，可用2D ZGR m描述不同类型的等温线。因此，证实了二维EOS具有可用于吸附剂材料的低压表征和高压吸附过程的潜力。
