Abstract: Gas separation modules and methods for use including an integrated adsorbent and membrane. In certain refining applications, it is paramount to obtain high purity product gases. Adsorbent beds are effective at removing certain contaminants, such as CO2, from gas streams containing product and contaminant constituents to form a product-rich stream. The integrated membrane permits a further separation of products from any unadsorbed contaminant to produce a high purity product, such as hydrogen, stream. The gas separation modules described herein include stacked, radial, and spiral arrangements. Each modules includes a configuration of feed and cross-flow channels for the collection of contaminant gases and/or high purity product gases.

Abstract: A process for separating dimethyl biphenyl (DMBP) isomers, including contacting a mixture of 3,3′-DMBP, 3,4′-DMBP and 4,4′-DMBP in a first solvent with a 12-member ring zeolite exchanged with potassium or barium, or combinations thereof, and adsorbing the 3,3′-DMBP onto the 12-member ring zeolite, such as by passing the mixture through at least one packed bed of the potassium and/or barium exchanged 12-member ring zeolite.

Abstract: In a process for separating one or more 3,3′-, 3,4′- and 4,4′-dimethyl biphenyl isomers, a feed comprising the isomers is contacted with a zeolite adsorbent which contains one or more metal cations in the +1 or +2 oxidation states. Separation processes for each of the 3,3′-, 3,4′- and 4,4′-dimethyl biphenyl isomers is provided.
