An adsorptive gas separation apparatus and method is disclosed. An adsorbent structure may include a first adsorbent layer having at least a first adsorbent material, a second adsorbent layer including at least a second adsorbent material, and a barrier layer, where the barrier layer is interposed between the first adsorbent layer and the second adsorbent layer. A parallel passage contactor including a plurality of adsorbent structures each comprising a barrier layer, and arranged to form first and second fluid passages is also disclosed. An adsorption process for separating at least a first component from a multi-component fluid stream using the adsorbent structure is also provided.

Methods and materials for the selective capture and storage of preselected materials from gas streams using metal organic framework (MOF) materials are described. In various embodiments preselected target material gases could include noble gasses such as Kr, Xe, Rn, Ar other gasses such as I.sub.2 or other particular isotopes either naturally occurring or man-made, or another preselected gas capture material such as a target material for legal, regulatory or treaty compliance, or a preselected material from a particular process such as a cleaning or etching agent from semiconducting or microelectronic manufacture, or a portion of an anesthetic gas such as nitrous oxide, isoflurane, sevoflurane or a fluorinated ethers.

Provided is an apparatus for the automated synthesis of at least one chemical compound including: at least one cartridge including at least one first compartment for providing at least one first reagent for the chemical synthesis of the at least one compound; at least one second compartment for providing at least one second reagent for the chemical synthesis of the at least one compound, and at least one third compartment for purifying the at least one synthesized compound; at least one reaction container for providing the compounds to be fed into at least one of the compartments of the cartridge and/or collecting the reaction product from at least one of the compartments of the cartridge; at least one solvent container at least two flow path selecting valves and at least one pump.

A metal trap for an FCC catalyst include pre-formed microspheres impregnated with a salt of calcium and/or magnesium and an organic acid salt of a rare earth element.

Provided is an unsaturated double bond-containing compound capable of sufficiently advancing a crosslinking reaction or a curing reaction when used for a coating material or the like and having oxygen absorption performance. The present invention also provides an oxygen absorbent containing the unsaturated double bond-containing compound and a resin composition containing the same. Provided are an unsaturated double bond-containing compound represented by general formula (I), an oxygen absorbent containing the same, and a resin composition.

The present disclosure relates to a mixed matrix carbon molecular sieve (CMS) membrane, a preparation method of the mixed matrix CMS membrane, and use of the mixed matrix CMS membrane in C.sub.2H.sub.4/C.sub.2H.sub.6 separation, and belongs to the technical field of membrane separation. The present disclosure solves the problem that the CMS materials in the prior art exhibit low selectivity and low flux during an ethylene/ethane separation process. In this patent, C.sub.3N.sub.4 is used as a filling particle to prepare a mixed matrix membrane (MMM), and the MMM is pyrolyzed to prepare a CMS membrane. The C.sub.3N.sub.4/6FDA-DAM MMM has prominent C.sub.2 separation performance.
