Abstract: Cross-linked cyclopolymeric resins from N,N-diallyl quaternary ammonium monomers and tetrallylpiperazinium cross-linking monomer or salts, solvates, tautomers or stereoisomers as adsorbent materials for the removal of heavy metals from aqueous solution. A process for producing the cross-linked cyclopolymeric resins by Butler cyclocopolymerization of the monomers with a free radical initiator. The cross linked cyclopolymeric resins are polyzwitterionic or polyzwitterionic and dianionic and feature repeating units with multiple chelating centers that heavy metal ions can bind to. In addition, a method for removing heavy metals from aqueous solution via contacting and treatment with the cross-linked cyclopolymeric resins.

Abstract: A method for separating natural gas liquids (NGLs) from a hydrocarbon gas mixture containing natural gas liquids and methane, comprising the steps of: i) providing a bed of adsorbent selective for NGLs over methane; ii) passing a hydrocarbon gas mixture containing methane and NGL through the bed of adsorbent to at least partially remove NGLs from the gas mixture to produce: (a) NGL-loaded adsorbent and (b) NGL-depleted hydrocarbon gas mixture; iii) recovering the NGL-depleted hydrocarbon gas mixture; iv) regenerating the NGL-loaded adsorbent by at least partially removing NGLs from the adsorbent; and v) sequentially repeating steps (ii) and (iii) using regenerated adsorbent from step (iv).

Abstract: The present invention relates to a super-absorbent polymer having excellent properties, both centrifugal retention capacity (CRC) and absorption under pressure (AUP) having been improved by introducing a surface crosslinked layer crosslinked by surface-modified inorganic particles, and to a method for preparing the same. The super-absorbent polymer comprises: a base resin powder containing a crosslinked polymer of water-soluble ethylene-based unsaturated monomers having an at least partially neutralized acidic group; and a surface crosslinked layer formed on the base resin powder, wherein inorganic particles may be chemically bound to the crosslinked polymer contained in the surface crosslinked layer, via an oxygen-containing bond or a nitrogen-containing bond.
