Abstract: Solid absorbent materials that are useful for absorption of chemical species from a fluid, such as a gas stream or a liquid stream. The absorbent materials are formed by spray processing and posses a well-defined chemical composition and microstructure. The absorbent materials can have a high absorption capacity for a chemical species such as H2S, CO2, NOx, and H2 and have a high recylability, such that the chemical species can be absorbed and desorbed over a large number of cycles.

Abstract: A zirconia-containing composition and processes for synthesizing same. The composition comprises least about 99.9 percent tetragonal phase zirconia, based on the total crystalline zirconia in the zirconia-containing composition as determined by x-ray diffraction (XRD). The composition also has a substantially spherical morphology and comprises less than 100 wppm chlorine, based on the total weight of the zirconia-containing composition. The zirconia-containing composition has an average surface area of at least 80 m2/g and an average particle size of less than about 10 microns.

Abstract: Security features, e.g., reflective security features, and processes for forming security features are described. The security features comprise crystalline metal-containing particles having a primary particle size of from about 10 nanometers to less than 500 nanometers and including a continuous or non-continuous coating of a ceramic material. Inks comprising such crystalline metal-containing particles are also described. The crystalline metal-containing particles are preferably produced by flame spraying.

Abstract: Materials that are useful for absorption enhanced reforming (AER) of a fuel, including absorbent materials such as Group 1 and Group 2 metal oxides that are adapted to absorb CO2 and catalyst materials such as reforming catalysts and water-gas shift catalysts, and methods for using the materials.

Abstract: The invention is directed to high surface area graphitized carbon and to processes for making high surface area graphitized carbon. The process includes steps of graphitizing and increasing the surface area of (in either order) a starting carbon material to form high surface area graphitized carbon. The step of increasing the surface area optionally comprises an oxidizing step (e.g., through steam etching) or template removal from composite particles. The invention is also directed to catalyst particles and electrodes employing catalyst particles that are formed from the high surface area graphitized carbon.

Abstract: Materials that are useful for absorption enhanced reforming (AER) of a fuel, including absorbent materials and catalyst materials, and methods for using such materials for the conversion of carbon-based fuels to a H2-rich product gas. The materials can be fabricated by spray processing. The use of the materials in AER can produce a H2 product gas having a high H2 content and a low level of carbon oxides. The method for converting carbon-based fuels to a H2-rich product gas includes forming an intermediate gas product from the carbon-based fuel using a catalyst and contacting the intermediate gas product with an absorbent to absorb CO2. The absorbent can be regenerated while retaining a high absorption capacity.

Abstract: Novel catalysts and processes in accordance with the invention can accomplish high selectivity and conversion of naphthalenic compounds such as the conversion of methylnaphthalene (2-MN) or naphthalene to 2,6-dimethylnaphthalene (2,6-DMN). The catalysts are prepared by treating, for example, a ZSM-5-type material with iron in the presence of a halogen such as a fluoride. The resulting catalyst includes iron, as well as a significant portion of aluminum present in the ZSM-5-type starting material. Processes for using the catalysts also are disclosed.
