Abstract: The present invention provides a zirconium-based metal-organic framework material and a preparation method therefor and the use thereof, and an adsorption separation device and method. The zirconium-based metal-organic framework material has a chemical structural formula of [C18H6O16Zr3]n, and comprises zirconium and an organic ligand forming a coordination bond with zirconium, wherein the organic ligand is diphenylethyne-3,3′,5,5′-tetracarboxylic acid. The molecular structure of the zirconium-based metal-organic framework material of the present invention is a three-position network structure having a one-dimensional channel; and in the present invention, the size of the one-dimensional channel is accurately controlled by changing the aspect ratio of the organic ligand, such that the zirconium-based metal-organic framework material efficiently separates a hexane isomer by means of a kinetic effect.

Abstract: The present invention relates, inter alia, to the use of porous crystalline solids constituted of a metal-organic framework (MOF) for the selective capture of volatile organic compounds (VOCs) comprising carboxylic acid functional group(s) and/or volatile organic compounds (VOCs) comprising an hydroxyl functional group.
The MOF solids of the present invention can be used for the purification of air, for example for the selective capture of VOCs comprising carboxylic acid functional group(s) and/or volatile organic compounds (VOCs) comprising an hydroxyl functional group from outdoor air. It may be used for art preservation, such as the conservation of cellulose derivate films, for indoor air purification systems such as HEPA air filters, adsorbent purifiers, kettle filters, fette filters, honeycomb filters or air conditioning filters, for outdoor air purification systems such as gas mask, nose filter, adsorption columns or chimney filters, and in cosmetic applications such as deodorants, anti-odor shampoo, hygienic protection products, wipes or diapers.-

Abstract: Thermoplastic compositions having reduced odor are described. A thermoplastic composition can include a thermoplastic polymer and a dual active functionalized silica (e.g., an amine-functionalized silica having a specific surface area of less than 450 m2/g and a nitrogen content of at least 1.2 wt. %). Such a thermoplastic composition has decreased odor-active volatile organic compounds (VOCs) emissions when compared with the same thermoplastic composition that does not include the dual active functionalized silica.

Abstract: This disclosure provides methods for separating multi-ring naphthenes from a hydrocarbon feedstock. The hydrocarbon feedstock includes at least normal paraffins, isoparaffins, 1-ring naphthenes attached with a paraffinic alkyl chain, and multi-ring naphthenes. The methods comprise passing the hydrocarbon feedstock and a solvent, at a temperature and pressure through a bed of an adsorbent comprising a metal-organic framework (MOF) adsorbent, to adsorb the multi-ring naphthenes from the hydrocarbon feedstock, thereby producing a base stock product that is depleted in multi-ring naphthenes. The metal-organic framework adsorbent is a porous crystalline material comprised of metal functionalities connected by organic linkers to form a repeating 2-D or 3-D lattice. The base stock product has a viscosity index (VI) greater than the viscosity index of the hydrocarbon feedstock. The methods of this disclosure upgrade Group II base stocks (also Group II+ base stocks) to Group III or Group III+ base stocks, and also upgrade Group III base stocks to Group III+ base stocks.
