Abstract: In a system for hydrogenation of an aromatic compound, an excessive temperature rise in the hydrogenation reaction unit is prevented, and the amount of the dilution gas to be circulated is minimized. The hydrogenation system (1) comprises a hydrogenation reaction unit (2) for producing a hydrogenated aromatic compound by adding hydrogen to an aromatic compound via a hydrogenation reaction, a separation unit (3) for separating the hydrogenated aromatic compound from a product of the hydrogenation reaction unit, and a transportation unit (4) for circulating at least a part of a residual component remaining in the separation unit after separating the hydrogenated aromatic compound therefrom to the hydrogenation reaction unit. The hydrogen supplied to the hydrogenation reaction unit consists of diluted hydrogen (L2) diluted by a dilution compound having a higher molar specific heat than nitrogen, and the dilution compound includes a component circulated to the hydrogenation reaction unit as the residual component.

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: 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.
