Industrial specifications require CO₂ concentrations in natural gas below 50 ppm during liquefaction because of corrosion and CO₂ freezing. Herein, we report a physisorbent (TIFSIX-3-Ni) that exhibits new benchmark CO₂/CH₄ selectivity and fast kinetics, thereby enabling one-step LNG processing to CO₂ levels of 25 ppm.

物理吸附剂用于一步法液化天然气处理的高选择性CO ₂去除

由于腐蚀和CO ₂冻结，工业规格要求液化期间天然气中的CO ₂浓度低于50 ppm 。在本文中，我们报告了一种表现出新的基准CO ₂ / CH ₄选择性和快速动力学的物理吸附剂（TIFSIX-3-Ni），从而能够一步一步将LNG加工至25 ppm的CO ₂水平。
