ヨルダン産天然ゼオライトを用いたCO吸着特性を評価。固定層カラムで圧力・温度・粒径の影響を調べ、Langmuir等温線に適合し飽和吸着容量は10.1 mg CO/g。温度上昇で吸着量減少、粒径減少で増加。吸着熱は55.5°C以下で発熱、以上で吸熱。
English
This study evaluates Jordanian natural zeolite for CO adsorption in a fixed-bed column, examining effects of pressure, temperature, and particle size. The Langmuir isotherm fits well, with saturation capacity of 10.1 mg CO/g. Adsorption decreases with temperature and increases with smaller particles. Heat of adsorption is exothermic below 55.5°C and endothermic above.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではCCUS技術開発が進むが、天然ゼオライトのCO吸着は新規性が低く、実用化にはコストやスケールの課題がある。日本の読者には基礎材料研究として参考になる程度。
In the global GX context
Globally, CCUS is a key decarbonization lever, but this study is a basic material characterization without direct policy or industrial application. It adds limited value to international CCUS scholarship, which focuses on scalable and cost-effective solutions.

📄 Abstract（原文）
The objective of this work was to evaluate Jordanian zeolitic tuff for adsorption of carbon monoxide. Samples of Jordanian naturally occurring zeolite were collected from southern Jordan at Al-Tafila Government/ Al Hala Volcano and physically treated then evaluated for adsorption of carbon monoxide in a fixed bed column. The effect of pressure, temperature, and zeolite particle size was studied. The adsorption isotherm and the heat of adsorption was obtained. The results indicated that the adsorption isotherm is in good fit with Langmuir adsorption isotherm, and the saturation adsorption capacity was found to be about 10.1 mg CO/g zeolite. The temperature and zeolite particle sizes were found to have significant effect on the adsorption. The adsorption loading decreased with temperature increasing and increased with decreasing particles sizes. An empirical equation for the dependance of adsorption loading on temperature and particle size was obtained and accordingly the heat of adsorption was obtained. The heat of adsorption was found to be exothermic below 55.5°C and endothermic above it.
