    Abstract: Thermally stable transitional alumina particulates retaining high specific surface area after calcination at 1000null C. suitable for the use as catalysts or catalysts supports are produced by treating an aqueous solution containing Al3null and optionally a doping amount of La3null (e.g., 0.3 mol. %) with an anion-exchange resin to give a stable hydroxide sol followed by freeze drying of the sol and further thermal dehydration. The resultant stabilized transitional alumina retains high specific surface area at 1000null C., and additionally stabilization is achieved at very low levels of added La.

    Abstract: A honeycomb body made from a ceramic material with improved radial pressure resistance that is of cylindrical shape and features a first and a second end face and a cylindrical shell and that is traversed from one end face to the other by axially parallel channels formed by channel walls and distributed across the cross section of the honeycomb body in a regular grid pattern, in which design an outer marginal zone of the honeycomb body, the thickness of which amounts to several channel diameters, encloses a central area. The increase in radial pressure resistance of the honeycomb body is achieved by reinforcing the ceramic material of the cylindrical shell and of the channel walls in the outer marginal zone of the honeycomb body by depositing on or in it one or several inorganic substances for the purpose of increasing its mechanical stability.

    Abstract: A titania-coated honeycomb catalyst matrix is provided for the ultraviolet-photocatalytic oxidation of organic pollutants in a flowing fluid. A honeycomb-shaped skeletal structure (12) has a thin, lightweight substrate (18) of metal or ceramic, typically an aluminum alloy, and a surface coating (20) of photocatalyst, such as titania. The photocatalyst (20) is bonded to the substrate (18) via a thin oxide layer (18null) on the substrate. The oxide layer (18null) may be grown on the substrate. The photocatalyst coating (20) is made by mixing (30) titania powder in a TiO2 sol-gel to form a titania slurry. The substrate with oxide layer is coated (30) with the titania slurry and then heat treated (31). The photocatalyst coating (20) is typically applied to substrate sheets (40, 60, 62) preformed for assembly into a honeycomb-shaped skeletal structure (12) having an array of parallel cells (46, 46null). The coated sheets (40) may have troughs (42) and crests (42), and be stacked (34) with intermediate parting sheets (48). Alternatively, the coated sheets (60, 62) may be notched (64) and interfitted in nulleggcratenull fashion. The honeycomb-shaped structure (12) is housed in a frame (50), and one or more stabilizer members (52) fastened to the frame serve to limit displacement of the structure as may be caused by the flowing fluid (14).

    Abstract: The present invention provides metal-exchanged hexaaluminate catalysts that exhibit good catalytic activity and/or stability at high temperatures for extended periods with retention of activity as combustion catalysts, and more generally as oxidation catalysts, that make them eminently suitable for use in methane combustion, particularly for use in natural gas fired gas turbines. The hexaaluminate catalysts of this invention are of particular interest for methane combustion processes for minimization of the generation of undesired levels (less than about 10 ppm) of NOx species. Metal exchanged hexaaluminate oxidation catalysts are also useful for oxidation of volatile organic compounds (VOC), particularly hydrocarbons. Metal exchanged hexaaluminate oxidation catalysts are further useful for partial oxidation, particularly at high temperatures, of reduced species, particularly hydrocarbons (alkanes and alkenes).
