“…For instance, CH 4 is regarded as a type of clean energy substitute to fossil fuel . C 2 H 6 is the main source for C 2 H 4 production, which is used as raw materials for various chemical reactions in petrochemical industry. , C 3 H 8 , as the main component of liquefied petroleum gas, is commonly used in C 3 H 6 production for synthetic materials . Nature gas is an important source of light hydrocarbons.…”

6 and C 3 H 8 adsorption capacities compared to HKUST-1 and some other metal− organic frameworks, which reached as high as 6.47 and 7.80 mmol/g at ambient conditions. Its C 2 H 6 /CH 4 and C 3 H 8 /CH 4 adsorption selectivities were up to 12.6 and 173.5, respectively. Fixed-bed experiments showed that 0.3Gly@HKUST-1 could separate the CH 4 /C 2 H 6 /C 3 H 8 mixtures completely at ambient conditions, showing excellent separation property toward the light hydrocarbons. More importantly, stability experiments confirmed that after the two samples were exposed to moist air (RH of 55%) for 20 days, 0.3Gly@HKUST-1 still remained its crystal structure, while parent HKUST-1 lost most of its crystallinity. Computational simulations showed that Gly grafting onto unsaturated Cu site played a critical role in enhancing stability against water vapor and improving capacity due to its shielding of unsaturated Cu site as well as introduction of −COOH or −NH 2 as the H-binding sites. Gly@HKUST-1 is promising for practical application of efficiently recovering ethane and propane from natural gas by adsorption.

“…Simultaneously, capturing and recovering C 2 H 6 and C 3 H 8 from CH 4 not only can improve the NG quality and increase the combustion efficiency, but also can yield vital raw materials for the manufacture of alkenes and polymers. [9][10][11] Currently, the purification technology of NG mainly depends on energyintensive cryogenic distillation according to the differences in boiling points (CH 4 112 K, C 2 H 6 184 K, and C 3 H 8 231 K) at low temperatures and high pressure 12,13 Although the cryogenic distillation process is industrially mature, it frequently suffers from high energy consumption, high input cost, harsh work conditions, and equipment corrosion. [14][15] Therefore, seeking advanced alternative methods with higher efficiency and lower carbon footprint for NG upgrading is a very imperative task.…”

“…Mostly, the selection of adsorbents for a specific purification task is based on experience [7]. Either for manual or automated experiments, for every purification task a new set of adsorbents is chosen covering a broad range of physical properties [16][17][18]. To address these challenges, adsorption selection diagrams were developed leading to specific adsorbents for various applications [19].…”

A systematic and automatic approach for adsorbent selection for liquid–phase adsorption is proposed. Based on physical properties like polarity, pore size, and specific surface, a screening strategy is developed and automated on a robotic platform. Key performance indicators are applied ensuring economically based decisions. The approach developed is verified by adsorption of caffeine out of an aqueous solution with vanillin, uracil, and α–ionon as impurities. The adsorbent selection strategy leads to the polymeric adsorbent SP207 and a specific surface of 15 m2mL−1 ending in a separation cost indicator of 16 € gCaffeine−1. This work proposes an opportunity for accelerated process design strengthened by the usage of robotic devices.
