  • Publication number: 20240216893
    Abstract: [Task] The task is to improve, in the hydrogenation of an aromatic halonitro compound, the yield of halogenated aromatic amine as a target product without the need for a dehalogenation inhibitor while suppressing the production of a nitroso compound. [Solution] A hydrogenation catalyst for hydrogenation of an aromatic halonitro compound includes: a carrier containing at least one of silica, titania, and alumina; and at least one metal carried by the carrier and selected from group 10 elements in a periodic table.

  • Patent number: 10472235
    Abstract: A method of manufacturing synthesis gas by catalytic partial oxidation can prevent formation of hot spots from taking place when driving mixture gas to pass through a catalyst-filled layer at high velocity. The method comprises converting mixture gas of source gas containing lower hydrocarbons and oxidative gas containing oxygen into synthesis gas containing hydrogen and carbon monoxide as main components thereof by causing mixture gas to flow through a fixed bed catalyst layer arranged in a reactor. The method of manufacturing synthesis gas by catalytic partial oxidation is conducted such that the mixture gas is made to flow to the catalyst layer under the condition that the Reynolds number does not exceed 20 at the inlet of the catalyst layer.

  • Patent number: 7285189
    Abstract: Disclosed is a novel method for steam reforming, by which selectivity to carbon monoxide is high, which is free from various side reactions, which may be carried out at a lower temperature and at a lower pressure than the conventional methods, and which may be carried out even if a catalyst is not used. In the method of the present invention, direct current pulse discharge is performed in a mixed gas containing a gaseous chain hydrocarbon and water vapor so as to react the chain hydrocarbon and the water vapor, thereby generating hydrogen and carbon monoxide.
