Abstract: A reactor using honeycomb catalyst is provided for fuel reformation with high activity and heat stability. The reactor comprises a heating tube, a methane gas inlet, a three-way steam inlet and a hydrogen-rich gas outlet. The three-way steam inlet is near to the heating tube for providing heat required for reformation and to reduce power consumption. The heating tube is made of an inconel material so that the overall reaction may be carried out at high temperature. The heating tube is set with a honeycomb carrier of cordierite. The honeycomb carrier is pasted with carbon nanotube and heat-treated to increase internal surface area. The honeycomb carrier has a Pt/CeO2/?-Al2O3 catalyst; is placed in the heating tube; and has honeycomb-pores channels parallel to a main axis of the heating tube.

Abstract: A gas-reforming catalyst is modified to obtain stability in high temperature. The catalyst uses ?-Al2O3 as a carrier and is nano-porous. Hence, reaction surface is greatly broadened; and platinum contained inside does not become bigger after times of use. The catalyst does not deposit carbon and has long life. The stability of the catalyst can be still remained even at a temperature higher than 800° C.

Abstract: The present disclosure provides a gas reaction device. Reactions are happened on a fixed bed and/or a slurry bed in four reaction states. Thus, by using the four reaction states, reactions are thoroughly completed with the same catalyst. Or, different reactions are completed with different catalysts for different purposes.

Abstract: A Cu—Zn—Al catalyst is fabricated for producing methanol and dimethyl ether (DME). A sol-gel method is used to obtain an organic phase with gel clusters rapidly transferred in. The catalyst thus fabricated can be adjusted in crystal grain size, crystal type, surface structure and active sites distribution. Thus, performance of the catalyst is improved.

Abstract: A method is disclosed for making Ru—Se and Ru—Se—W catalyst. In the method, carrier is processed with strong acid and poured into first ethylene glycol solution. Ultra-sonication and high-speed stirring are conducted on the first ethylene glycol solution, thus forming carbon paste. The carbon paste is mixed with second ethylene glycol solution containing at least one nanometer catalyst precursor and an additive. High-speed stirring is conducted to form mixture. The mixture is heated so that Ru—Se catalyst is reduced. The mixture is filtered to separate the carrier. Then, the carrier is washed with de-ionized water. Conducting drying and hydrogen reduction are conducted to make the Ru—Se catalyst on the carrier.

Abstract: Fuel cell electrodes are fabricated on electrode base substrates. The electrode substrates can be evenly and uniformly covered with electrocatalysts, which are supported on carbon nanomaterials, and ionomers by means of filtration and pressing. The electrodes can be used as anodes or cathodes for membrane fuel cells, such as DMFC and PEMFC.

Abstract: This invention relates to the preparations of noble metal catalysts, i.e., platinum and platinum alloys, on suitable supports with nanonetwork structures and high catalytic efficiencies. A compact structure of a monolayer or a few layers is formed by self-assembly of organic polymer, e.g., polystyrene (PS), nanospheres or inorganic, i.e., silicon dioxide (SiO2), nanospheres on a support surface. In the void spaces of such a compact arrangement, catalyst is formed by filling with catalyst metal ion-containing aqueous solution and reduced by chemical reduction, or formed by vacuum sputtering. When using organic polymer nanospheres as the starting or structure-directing material, the polymer particles are removed by burning at a high temperature and the catalyst having a nanonetwork structure is obtained.
