Abstract:
Attrition resistant, sorbent compositions for the removal of elemental sulfur and sulfur compounds, such as hydrogen sulfide and organic sulfides, from cracked-gasoline and diesel fuels are prepared by the impregnation of a sorbent support comprising zinc oxide, expanded perlite, and alumina with a promoter such as nickel, nickel oxide or a precursor of nickel oxide followed by reduction of the valence of the promoter metal in the resulting promoter metal sorbent support composition.
Abstract:
A metal-organic framework (MOF) polymer for solid-phase microextraction (SPME) includes an MOF including metal ions building units coordinating polytopic organic linkers; and a polymer coordinatively bonding to the MOF, wherein the polymer is composed of one or more vinyl monomers and a cross-linker those are polymerized in the presence of a radical initiator. A method for preparing a stationary phase for SPME is also provided.

Abstract:
Plate-shaped composite getter materials for the sorption of gases containing two interpenetrating constituents, a reinforcing component of skeletal framework and a reactive matrix, which form a coherent monolithic structure, a method for producing such composites, and their application in vacuum technology or gas purification are described. A synthetic getter composite of the classical type in the form of a thin monolithic plate with two constituents, a reinforcing framework embedded in a reactive matrix, has been developed. Metallic gauze made of high-melting transitional metals or their alloys is used as a reinforcing constituent and a reactive metal or alloy with a high concentration of this metal is used as the reactive matrix.
