(Nanowerk Spotlight) The petrochemical industry relies on separating chemicals that differ by just fractions of a nanometer in size. Methanol must be purified from similarly-sized molecules in the ...

Ultrathin 2D metal-organic framework (MOF) membranes, with their highly tunable pore structures, ultrahigh pore density, and nanoscale thickness, are ideal materials for achieving both high ...

A recent study evaluated the different treating processes that remove carbonyl sulfide (COS) from propane streams. The study grouped seven different process types into nonregenerable, regenerable, and ...

Natural gas treatment often uses adsorbents for contaminant removal. Special materials, such as molecular sieves, remove sulfur-containing impurities like mercaptans, as well as water vapor. Such ...

Iron-based molecular sieves show great promise for high-temperature NH3-SCR due to their intrinsic shape selectivity and thermal stability. However ...
