A dehydrogenation reaction apparatus and a system including the same are disclosed. The dehydrogenation reaction apparatus includes: a main housing; and a dehydrogenation reactor which is provided inside of the main housing and has a catalyst provided inside. In particular, the dehydrogenation reactor generates hydrogen from a liquid organic hydrogen carrier (LOHC). The dehydrogenation reaction apparatus further includes: a heating device provided inside of the main housing and configured to apply heat to the dehydrogenation reactor through a phase change material, where the phase change material is provided between the main housing, and the dehydrogenation reactor and the heating device.

Dehydrogenation reaction apparatus and system including the same

A catalyst for a dehydrogenation reaction includes a carrier including AlOhaving a theta (θ) phase, an active metal supported on the carrier and including a noble metal, and an auxiliary metal supported on the carrier and different from the active metal.

Catalyst for a dehydrogenation reaction, a manufacturing method thereof, and a hydrogen production method using same

A dehydrogenation reaction apparatus includes a dehydrogenation reactor having a reaction vessel that stores a chemical hydride; and a methane generator that converts carbon monoxide generated in the dehydrogenation reactor into methane.

Dehydrogenation reaction apparatus

The present specification discloses a membrane reactor comprising a reaction region; a permeate region; and a composite membrane disposed at a boundary of the reaction region and the permeate region, wherein the reaction region comprises a bed filled with a catalyst for dehydrogenation reaction, wherein the composite membrane comprises a support layer including a metal with a body-centered-cubic (BCC) crystal structure, and a catalyst layer including a palladium (Pd) or a palladium alloy formed onto the support layer, wherein ammonia (NH) is supplied to the reaction region, the ammonia is converted into hydrogen (H) by the dehydrogenation reaction in the presence of the catalyst for dehydrogenation reaction, and the hydrogen permeates the composite membrane and is emitted from the membrane reactor through the permeate region.

Ammonia membrane reactor comprising a composite membrane

A hydrogen generating method includes generating hydrogen by dehydrogenation-reacting a chemical hydride of a solid state with an acid aqueous solution. The dehydrogenation-reaction is performed by reacting 1 mol of hydrogen atoms of the chemical hydride with an acid and water at a molar ratio of 0.5 to 2.

Method for generating hydrogen

According to one embodiment of the present invention, there is provided a hydrogen extraction reactor, comprising a chamber including an inner space; a reaction unit which is provided to pass through the inside of the chamber and where an endothermic reaction for hydrogen extraction occurs; a heating unit which is provided to be spaced apart from the reaction unit inside the chamber and transfers heat to the inside of the chamber; and a heat transfer material which is provided between the reaction unit and the heating unit in the chamber, wherein the heat transfer material undergoes a phase transition between a gas phase and a liquid phase according to the entry and exit of heat from the heating unit or the reaction unit.
