摘要:Disclosed are a catalyst for producing a synthesis gas using a carbon-containing organic compound as a raw material and a process for producing carbon monoxide. The catalyst for producing a synthesis gas is composed of a carrier formed of a metal oxide and at least one catalytic metal selected from rhodium, ruthenium, iridium, palladium and platinum and supported on the carrier and is characterized in that the catalyst has a specific surface area of 25 m 2 /g or less, in that the electronegativity of the metal ion of the carrier metal oxide is 13.0 or less and in that the amount of the supported catalytic metal is 0.0005-0.1 mole %, in terms of a metal, based on the carrier metal oxide. The process for producing carbon monoxide includes a step of reacting a carbon-containing organic compound with carbon dioxide in a pressurized condition to produce a synthesis gas, and a step of concentrating carbon monoxide in the thus obtained synthesis gas and is characterized in that the above-described catalyst is used as a catalyst in the synthesis gas producing step.

摘要:Disclosed is a process for producing a synthesis gas by an autothermal reforming method including a step of partially oxidizing a carbon-containing organic compound to produce a high temperature mixed gas, and a synthesis producing step of reacting the unreacted carbon-containing organic compound contained in the high temperature mixed gas with carbon dioxide and/or steam, wherein a catalyst having a considerably suppressed carbon deposition activity is used as a catalyst for the synthesis gas producing step. The catalyst is characterized in that the catalyst comprises a carrier formed of a metal oxide, and at least one catalytic metal selected from rhodium, ruthenium, iridium, palladium and platinum and supported on the carrier, in that the catalyst has a specific surface area of 25 m 2 /g or less, in that metal ion of the carrier metal oxide has electronegativity of 13.0 or less, and in that the amount of the catalytic metal supported is 0.0005-0.1 mole %, in terms of a metal, based on the carrier metal oxide.

摘要:Metal-doped hydroxyapatite catalysts for isobutanol and propanol synthesis have been developed which exhibit good isobutanol yield in propanol-methanol and ethanol-methanol reactions. The metal-doped hydroxyapatites include, but are not limited to, one or more of metal-doped Mg x PO y , Ca x PO y , Sr x PO y and Ba x PO y . The metal-doped hydroxyapatites may have different phosphorus to alkaline earth ratios. Methods for making isobutanol and propanol using the metal-doped hydroxyapatite catalysts are also provided.

摘要:The present application provides a preparation method for iridium nanocrystal, including the following steps: mixing an iridium salt, an alcohol solvent and a centrifugal waste liquid to form a mixed solution, and adding an alkali solution in an inert atmosphere for a heating reaction. After centrifugation, an iridium nanocrystal is obtained. The centrifugal waste liquid is a waste liquid produced in the pre-synthesis process of iridium nanocrystal. The preparation method can shorten the reaction time, and the obtained iridium nanocrystal has the advantages of high yield and low cost.
