摘要： To provide an apparatus and a system suitable for continuously and stably producing hydrogen by taking advantage of a direction composition reaction of hydrocarbons as well as a method for separating a solid product.
Provided are a hydrogen producing apparatus using a nickel-based metal structure for the direct decomposition reaction of hydrocarbons and a discharging and recovering system comprising: a depressurization chamber communicating with a lower opening of the reaction chamber of hydrogen producing apparatus 1 via a ventilation hole; a first valve capable of opening and closing said ventilation hole; a collection box communicating with the depressurization chamber via a channel; a second valve capable of opening and closing said depressurization chamber; and a depressurization pump communicating with the collection box.

摘要： A catalyst for decomposition of hydrocarbons that is hard to cause deterioration of catalytic properties and suitable for producing hydrogen in a highly efficient manner for a long period is provided. The catalyst for the decomposition of hydrocarbons includes a nickel-containing layer exposed on a support layer selected from the group consisting of iron, cast iron, steel, copper, nickel, copper alloy, and iron nickel alloy. The catalyst for decomposition of hydrocarbons is produced by contacting a raw material of the catalyst with methane gas at an elevated temperature of 800° C. for 4 to 72 hours with an average residence time beyond 14 minutes. The catalyst further includes an interlayer comprising copper between the support layer and the nickel-containing layer, or the support layer is copper or copper alloy.

摘要： A reactor for the decomposition of hydrocarbons includes: a structural catalyst for the decomposition of hydrocarbons having a structure in which a reaction gas may flow from one end to the other end when installed properly in a reaction chamber; and the heat source that is installed inside or outside the reaction chamber and capable of heating the structural catalyst for the decomposition of hydrocarbons. The structural catalyst for the decomposition of hydrocarbons has a shape encompassing a boundary wall surface or a boundary side that separates the structural catalyst for the decomposition of hydrocarbons from the heat source when viewed from a cross-section vertical to a direction of flowing a reaction gas, as well as the reaction furnace in which the reactor is embedded together with a catalyst module.
