Abstract:
... Lignocellulosic biomass-derived ethanol offers a potential alternative to fossil-derived fuels. However, the energy-intensive nature of its recovery process, i.e., a sequence of two distillation columns – beer and rectification columns - enriching from 5 to 37, and 37–93wt%, respectively, limits its environmental and economic benefits. In this paper, we assess the potential of using zeolite membra ...

Subject:
adsorbents; biological properties and phenomena; carbon nanotubes; energy; geometry; hydrogen bonding; hydrophilicity; hydrophobicity; mathematical theory; molecular dynamics; nanopores; simulation models; zeolites
Abstract:
... The properties of confined water are relevant to many chemical, geological, and biological phenomena, where they underpin essential changes to molecular scale reactivity–perturbing both the energetic and configurational landscape. Though much prior literature has focused on hydrophilic confinement, the hydrophobic confinement of water is less well understood. Here, we use molecular dynamics simula ...

Subject:
Fourier transform infrared spectroscopy; acetone; adsorption; aqueous solutions; butanol; distillation; energy efficiency; ethanol; fermentation; fluorides; hydrophilicity; hydrophobicity; pH; vapors; zeolites
Abstract:
... A promising route for sustainable 1-butanol (butanol) production is ABE (acetone, butanol, ethanol) fermentation. However, recovery of the products is challenging because of the low concentrations obtained in the aqueous solution, thus hampering large-scale production of biobutanol. Membrane and adsorbent-based technologies using hydrophobic zeolites are interesting alternatives to traditional sep ...

Subject:
absorption; adsorbents; adsorption; composite materials; coordination polymers; distillation; hydrogen sulfide; ionic liquids; metals; oil and gas industry; oxides; zeolites
Abstract:
... Hydrogen sulfide removal is a long-standing economic and environmental challenge faced by the oil and gas industries. H₂S separation processes using reactive and non-reactive absorption and adsorption, membranes, and cryogenic distillation are reviewed. A detailed discussion is presented on new developments in adsorbents, such as ionic liquids, metal oxides, metals, metal–organic frameworks, zeoli ...
