Abstract: An improved, conductive, polymeric composition comprises a polymeric resin; an electrically conductive filler system comprising small carbon fibers and either carbon powder or fibrous non-conductive filler or a combination of both. The amount of the conductive filler system utilized is dependent upon the desired electrical conductivity (surface and volume conductivity or resistivity) while preferably preserving intrinsic properties of the polymeric resin such as impact, flex modulus, class A finish, and the like. The conductive articles made from these compositions can therefore be used for electromagnetic shielding, electrostatic dissipation or antistatic purposes in packaging, electronic components, housings for electronic components and automotive housings.

Abstract: A hydrophobicity imparting particulate is provided in the present invention. A silicone composition comprises (A) a silicone polymer and (B) a hydrophobicity imparting particulate filler that imparts a hydrophobicity property to the composition. An insulator comprises a housing portion that includes a cured product of (A) a silicone polymer and (B) a hydrophobicity imparting particulate filler. A hydrophobicity recovery property of a silicone polymer composition can be improved by determining a target hydrophobicity recovery property for the cured silicone composition, selecting a hydrophobicity imparting particulate (HIP) to impart the hydrophobicity recovery property to the silicone polymer composition and compounding a blend of (A) a silicone polymer and (B) the selected inorganic filler and heating to cure the blend.

Abstract: A process for removing and then capturing noxious sulfur oxides from gas streams, particularly from the flue gases of coal-burning power plants, using Ni-containing heated layered double hydroxide (LDH) as recyclable sorbents. The sorbent compositions contain metal components that form stable metal sulfites and sulfates at one temperature, but are decomposed at a higher temperature to regenerate the sorbent material.

Abstract: The use of base/clay composites materials as sorbents for the removal of SO.sub.2 and SO.sub.3 (SO.sub.x) from flue gas and other sulfur containing gas streams is described. The base is either an alkaline earth metal carbonate (eg. CaCO.sub.3) or hydroxide (eg. Ca(OH).sub.2) is incorporated onto the clay by precipitating from corresponding metal oxide (eg. CaO) in an aqueous clay slurry. A second metal oxide or oxide precursor, preferably selected from transition metal ions, capable of promoting the oxidation of sulfur dioxide to sulfur trioxide, is incorporated to the base/clay composite during the synthesis in the form of finely divided metal oxide powder, metal oxide sol, water soluble metal salt or as clay-intercalated metal cation. The use of clay as dispersing agent for both the basic oxide and the second metal oxide component decreases the particle agglomeration of base particles and increases the rate of SO.sub.x uptake compared to the bulk bases in current use.

Abstract: A process for removing noxious sulfur oxides, nitrous oxides, and chlorine from gas streams, particularly from flue gases of coal-burning power plants, using layered double hydroxide (LDH) sorbents are described. The sorbents are particularly useful for SO.sub.2 absorption at temperatures in the range 100 to less than 400.degree. C. The SO.sub.2 gas absorbs into the hydrotalcite structure as SO.sub.3.sup.2- anions by replacing most of the gallery CO.sub.3.sup.2- anions. The adsorbed SO.sub.2 is driven-off by calcination at elevated temperatures (500.degree. C.) and the LDH sorbents are regenerated by hydrolyzing the calcined product optionally in the presence of CO.sub.2 or CO.sub.3.sup.2-.

Abstract: The preparation and the use of base/clay composites materials as sorbents for the removal of SO.sub.2 and SO.sub.3 (SO.sub.x) from flue gas and other sulfur containing gas streams is described. The base is either an alkaline earth metal carbonate (e.g. CaCO.sub.3) or hydroxide (e.g. Ca(OH).sub.2) and is incorporated onto the clay by hydrating a dry physical mixture of an alkaline earth metal oxide, a smectite clay and a second metal oxide, or metal oxide precursor to form a powdered composite material. The second metal oxide, preferably selected from transition metal ions, act as an oxidation catalyst for the conversion of sulfur dioxide to sulfur trioxide. The use of clay as dispersing agent for both the basic oxide and the catalytic oxide component decreases the particle agglomeration of base particles and increases the rate of SO.sub.x uptake compared to the bulk bases in current use.
