Publication number: 20100152038Abstract: Industrial waste derived adsorbents were obtained by pyrolysis of sewage sludge, metal sludge, waste oil sludge and tobacco waste in some combination. The materials were used as media to remove hydrogen sulfide at room temperature in the presence of moisture. The initial and exhausted adsorbents after the breakthrough tests were characterized using sorption of nitrogen, thermal analysis, XRD, ICP, and surface pH measurements. Mixing tobacco and sludges result in a strong synergy enhancing the catalytic properties of adsorbents. During pyrolysis new mineral phases are formed as a result of solid state reaction between the components of the sludges. High temperature of pyrolysis is beneficial for the adsorbents due to the enhanced activation of carbonaceous phase and chemical stabilization of inorganic phase. Samples obtained at low temperature are sensitive to water, which deactivates their catalytic centers.Type: ApplicationFiled: November 4, 2009Publication date: June 17, 2010Applicant: Research Foundation of the City University of New YorkInventor: Teresa J.

The composition includes an amino silane and a multivalent metal carbonate and is especially suitable for adding to building product board substrates, such as acoustical ceiling panels and gypsum wallboards. The composition of the invention can be applied during manufacturing or can be post applied to already constructed room surfaces. The composition provides longevity of aldehyde removal heretofore unachieved.Type: ApplicationFiled: July 20, 2009Publication date: January 21, 2010Inventors: William Barrows, Gourish Sirdeshpande, Kenneth G. Caldwell, John R. Garrick, Michael Cook

Publication number: 20100016151Abstract: The invention is a surface coating which will reduce the aldehyde concentration in a room via a aldehyde reactive material contained in the coating. Upon reaction, the aldehyde becomes part of the reactive molecule and, thus, is permanently held within the coating.Type: ApplicationFiled: July 20, 2009Publication date: January 21, 2010Inventors: Kenneth G. Caldwell, Gourish Sirdeshpande, William Barrows, John R. Garrick, Michael Cook

Patent number: 7638570Abstract: There is disclosed a water-absorbing agent which combines both performances of the capillary suction force and the liquid permeability. This water-absorbing agent is a particulate water-absorbing agent comprising water-absorbent resin particles (?) and a liquid-permeability-enhancing agent (?), wherein the water-absorbent resin particles (?) are surface-crosslink-treated particles of a crosslinked polymer of a monomer including acrylic acid and/or its salt; with the water-absorbing agent being characterized in that the particulate water-absorbing agent has: a mass-average particle diameter (D50) in the range of 234 to 394 gm, a logarithmic standard deviation (??) of a particle diameter distribution in the range of 0.25 to 0.45, an absorption capacity without load (CRC) of not less than 15 g/g, and a water-extractable component content of not higher than 15 mass %; and further a liquid-permeability-enhancing agent (?) content in the range of 0.Type: GrantFiled: February 2, 2004Date of Patent: December 29, 2009Assignee: Nippon Shokubai Co., Ltd.Inventors: Kazushi Torii, Yoshiro Mitsukami, Motohiro Imura, Taku Iwamura
