The present invention relates unique pore structures in nickel supported on alumina with the negligible formation of macropores. Incorporation of additional elements stabilizes the pore structure of the nickel supported on alumina. Additional element(s) were then further added into the nickel-supported materials. These additional element(s) further stabilize the pore structures under heating conditions. The improvements of pore structure stability under heating conditions and negligible presence of macropores limit the sintering of nickel metal to a mechanism of impeded diffusion. The negligible presence of macropores also limits the deposition of alkali metal hydroxide(s)/carbonate(s) to the outer shell of the catalyst pellet. Both of the negligible presence of macropores and improvement in pore structure stability allow for prolonging the catalyst life of these nickel supported on alumina catalysts of the present invention for reforming hydrocarbons.

Catalytic adsorbents obtained from municipal sludges, industrial sludges, compost and tobacco waste and process for their production

Автор: Teresa J. Bandosz
Принадлежит: Research Foundation Of City University of New York

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.

The process comprises: (a) combining aluminum oxide, metal compound capable of forming spinel phase, and soluble compound of a trivalent aluminum; (b) mixing the combination resulting in (a) in a manner sufficient to form a slurry comprising the aforementioned combination; and (c) processing the mixture of (b) under conditions sufficient to form metal aluminate spinel composition. Metal aluminate spinel, for example, is formed in the last step by calcining the mixture from (b) at a temperature in the range of 700 to 1300° C., but the process is also capable, of producing attrition resistant supports (e.g., having a DI of 5 or less) at a relatively lower temperature in the range of 700 to 1050° C. The invention also produces the attrition resistance with lower metal loadings than that reported for prior attrition resistant spinel supports.

Номер: US20130280128A1
Автор: David A. Kidwell
Принадлежит: Individual

A method for producing excess enthalpy by impregnating metallic precursors on an oxide support that reduces sintering and particle growth; drying the impregnated support at a temperature where the particle growth is minimal; reducing the metallic precursors at a second temperature where the particle growth results in supported metallic particles 2 nm or less in size; and pressurizing the supported metallic particles in the presence of deuterium. The metal particles may comprise palladium, platinum, mixtures thereof, or mixtures of palladium and/or platinum with other elements. Also disclosed is a method for measuring excess enthalpy by placing a test material in a pressure vessel; heating the pressure vessel; evacuating the pressure vessel; introducing deuterium, hydrogen, or both into the pressure vessel; measuring the enthalpy generated during pressurization; again evacuating the pressure vessel; and measuring the enthalpy used during depressurization.
