Nickel-based reforming catalyst

Номер: US20130053237A1
Автор: David Beijia Xu, Wen-Qing Xu
Принадлежит: Individual

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.

The PCS possesses porous surface and internal coralloid-like channel structure that can accommodate high amount of iron-containing materials and derivatives thereof. The surface pore size, porosity, hydrophilicitv, and internal coralloid-like channel structure of PCS can be tailored through the manufacturing process, with which PCS can be functioned as a regulator for the releasing of produced hydrogen, and also control the adsorption and reactions toward heavy metals and chlorinated volatile organic compounds in water. The hydrogen released from the ZVM-PCS can be applied to anaerobic bioremediation. Moreover, the ZVM-PCS can be filter materials that can be installed in a column or any storage for water and wastewater treatment, or even in a groundwater cut-off barrier for the cleanup of contamination. While the ZVM-PCS is synthesized as a film without surface openings, it can be used as the electromagnetic interference (EMI) shielding material.

Принадлежит: BROOKHAVEN SCIENCE ASSOCIATES LLC

High-surface-area carbon nanostructures coated with a smooth and conformal submonolayer-to-multilayer thin metal films and their method of manufacture are described. The manufacturing process may involve initial oxidation of the carbon nanostructures followed by immersion in a solution with the desired pH to create negative surface dipoles. The nanostructures are subsequently immersed in an alkaline solution containing non-noble metal ions which adsorb at surface reaction sites. The metal ions are then reduced via chemical or electrical means and the nanostructures are exposed to a solution containing a salt of one or more noble metals which replace adsorbed non-noble surface metal atoms by galvanic displacement. Subsequent film growth may be performed via the initial quasi-underpotential deposition of a non-noble metal followed by immersion in a solution comprising a more noble metal. The resulting coated nanostructures may be used, for example, as high-performance electrodes in supercapacitors, batteries, or other electric storage devices.
