copper trimesate (cu-btc) mof has been pointed out as a promising adsorbent for separating carbon dioxide from methane. however, mof’s need to be shaped prior to their use in packed bed adsorbers in order to reduce pressure drop; on the other hand, the production of mechanically resistant shaped bodies reduces their adsorption performance. in this work, cu-btc tablets provided by basf are evalu...

Ein poröser Molekülkristall aus makrozyklischem Cyclotetrabenzoinacetat fängt effizient CO2 ein, wie Ognjen Š. Miljanić, Teng-Hao Chen und Mitarbeiter in ihrem Forschungsartikel auf S. 15058 berichten. Die quadratischen 7.1×7.1 Å großen Poren ermöglichen eine exzellente CO2/N2- CO2/CH4-Trennleistung sowohl durch kinetische als auch thermodynamische Effekte. Mäßig starke CO2-Gerüst-Wechselwirkun...

In this study, a water- and heavy hydrocarbon-removal process of natural gas refinery currently in operation using the temperature swing adsorption method is modeled investigated. The aim to decrease hydrocarbon dew point −10 °C diminish water content about 0.1 ppm. This unit consists four beds with two layers which are state, while others kept regeneration state. composition bed specification ...

Zeolite-based honeycomb rotors have been successfully used for VOC capture in various industries due to advantages of low pressure drop, fast response temperature swing desorption and outstanding adsorption characteristics. However, the high cost fragile nature ultrathin ceramic fiber paper assembling carrier created issues its commercial applications. Herein, a novel based on stainless-steel w...

A key parameter for the application of polymer gels in water shut off treatment is the adsorption of polymer gel onto the rock surface. So, the adsorption properties of a nanocomposite hydrogel were discussed in this research by crosslinking of sulfonated polyacrylamide/sodium montmorillonite aqueous solutions with chromium triacetate. The X-ray diffraction patterns indicated that exfoliated ty...

Integrated gasification combined cycle with CO 2 capture and sequestration (IGCC-CCS) emerges as one of the most promising technologies for reducing CO 2 emission from coal power plant without reducing thermal efficiency significantly. However the high capital cost of these plants has limited their deployment. The current solvent-based low-temperature CO 2 capture process (Selexol process) is e...
