  • Publication number: 20220168723
    Abstract: A method for forming a carbon-carbon bond, wherein a reaction is performed by filling a platinum group metal-supported catalyst into a filling container, and passing a raw material liquid through the platinum group metal-supported catalyst in a continuous circulation manner, and wherein the platinum group metal-supported catalyst is a platinum group metal-supported catalyst in which nanoparticles of a platinum group metal with an average particle diameter of 1 to 100 nm are supported on a non-particulate organic porous ion exchanger formed of a continuous framework phase and a continuous pore phase.

  • Publication number: 20210206632
    Abstract: A device includes: a storage section which stores a solution containing an organic compound; a catalyst holding section to hold a solid catalyst; and a microwave irradiation mechanism which irradiates the solution passing through the catalyst holding section with a microwave, wherein the solid catalyst is a molded catalyst containing a noble metal supported on a carrier that has an average particle diameter larger than 100 ?m. A hydrogen production method includes irradiating a solution containing an organic compound, the solution passing through a catalyst holding section holding a solid catalyst, with a microwave, the solid catalyst being a molded catalyst containing a noble metal supported on a carrier that has an average particle diameter larger than 100 ?m. Both device and method do not require a high-temperature heat source, enable easy collection, replacement, of the catalyst, and can be used for production of hydrogen.

  • Publication number: 20210130255
    Abstract: A hydrocarbon is produced by applying mechanical energy to a metal body containing stainless steel by solid-solid contact so that a contact pressure per unit area is 30 kPa or more, in the presence of a gas containing carbon dioxide and a hydrogen source, thereby adding hydrogen to carbon dioxide. Further, a hydrocarbon is produced by providing a reaction vessel for applying mechanical energy to a metal body by solid-solid contact in the presence of a gas containing carbon dioxide and a hydrogen source, a gas introduction unit for introducing the gas containing carbon dioxide to the reaction vessel, a hydrogen source introduction unit for introducing the hydrogen source to the reaction vessel, and a gas discharge unit for discharging a gas containing the hydrocarbon produced in the reaction vessel, and adding hydrogen to the carbon dioxide in the reaction vessel.
