The present invention discloses microporous UZM-5 zeolite membranes, methods for making the same, and methods of separating gases, vapors, and liquids using the same. The small-pore microporous UZM-5 zeolite membrane is prepared by two different methods, including in-situ crystallization of one or more layers of UZM-5 zeolite crystals on a porous membrane support, and a seeding method by in-situ crystallization of a continuous second layer of UZM-5 zeolite crystals on a seed layer of UZM-5 zeolite crystals supported on a porous membrane support. The membranes in the form of disks, tubes, or hollow fibers have superior thermal and chemical stability, good erosion resistance, high CO2 plasticization resistance, and significantly improved selectivity over polymer membranes for gas, vapor, and liquid separations.

A hydrophilic composition for use with a lubricating system comprises hydrophilic fibers having a diameter between 50 nm and 10 microns and a length that is at least 5 times the diameter. The hydrophilic fibers having a strong affinity for water and/or other hydrophilic fluids and may remove or eliminate free or dissolved water in a lubricating system comprising oil and/or lubricating fluid.
摘要:
An apparatus is disclosed for use in a system containing oil and/or lubricating fluid. The apparatus comprises a surface (1) in need of lubrication during operation of the apparatus, and oleophilic fibers disposed on the surface. The oleophilic fibers have a diameter between 50 nm and 10 microns and a length that is at least 5 times the diameter. In addition, the oleophilic fibers have an affinity for the oil and/or lubricating fluid.

摘要:
Adsorptive ultra-fine metal particles having a bond between an organic acid component and a metal, and exhibiting an infrared absorption peak derived from the bond between the organic acid component and the metal near 1518 cm -1 . The adsorptive ultra-fine metal particles are capable of exhibiting excellent deodorizing property and VOC-adsorbing property without impairing properties and formability of the resin. The invention is further concerned to an adsorptive resin composition and an adsorptive coating material containing the adsorptive ultra-fine metal particles and are capable of forming shaped resin articles or coatings.
