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.

Abstract: To reduce the emission of carbon dioxide and improve the energy efficiency in a hydrogen supply system. The hydrogen supply system (1) comprises: a reformer (5) for performing steam reforming of a hydrocarbon; a shift reaction unit (6) for producing a gas containing hydrogen and carbon dioxide by causing a water gas shift reaction of a gas obtained from the reformer; a first absorber (36) for absorbing the carbon dioxide contained in the gas obtained from the shift reaction unit in an absorption liquid; a hydrogenation reaction unit (8) for producing a hydrogenated aromatic compound by causing a hydrogenation reaction of an aromatic compound with a gas that has passed through the first absorber; and a regenerator (37) for separating the carbon dioxide from the absorption liquid by re-circulating the absorption liquid from the first absorber and heating the absorption liquid with heat generated from the hydrogenation reaction.

Abstract: To allow hydrogen to be supplied to a dehydrogenation reaction unit for dehydrogenating an organic hydride by using a highly simple structure so that the activity of the dehydrogenation catalyst of the dehydrogenation reaction unit is prevented from being rapidly reduced.

Abstract: The energy is minimized that is required to lower the concentration of the high boiling point components (containing the poisoning substance for the dehydrogenation catalyst) contained in the hydrogenated aromatic compound produced by the hydrogenation of an aromatic compound. The hydrogenation system (2) for an aromatic compound comprises a hydrogenation reaction unit (11) for adding hydrogen to an aromatic compound by a hydrogenation reaction to produce a hydrogenated aromatic compound, a first separation unit (12) for separating a gas and a liquid component from a product of the hydrogenation reaction unit while maintaining a temperature of the product generally higher than a boiling point of the hydrogenated aromatic compound, and a second separation unit (13) for separating the hydrogenated aromatic compound from the gas component separated by the first separation unit.
