A hydrogen production reactor

Abstract

The present invention relates to a reactor for producing a reformed gas containing hydrogen by a raw material containing a carbon compound and water, the reactor comprising: a reforming unit for reforming the raw material to produce a reformed gas containing hydrogen; a combustion unit supplying heat to the reforming unit by burning the raw material; a carbon monoxide removal reaction section for removing carbon monoxide in the reformed gas containing hydrogen; a heated raw material feeding pipe; and a reformed raw material phase change tube which is located in the combustion unit and used for heating the raw material. A first housing, a second casing, and the heated raw material feed pipe are provided in this order from the outside in a concentric structure, and the reforming unit and the combustion unit are respectively and independently formed by the space between the first housing and the second housing and the space between the second housing and the heated raw material feed pipe.

Description

technical field [0001] The present invention relates to a hydrogen production reactor which reforms carbon compounds into reformed gas containing hydrogen and supplies it to a fuel cell. Specifically, it relates to a hydrogen production reactor for producing hydrogen from carbon compounds by evaporating the raw material gasified in the phase change part of the liquid raw material mixed with carbon compounds and water in a reforming reaction part filled with a catalyst In order to promote the reaction, a combustion reaction part is set on the adjacent flow path separated from the reforming reaction part, and a part of the liquid raw material is induced to carry out combustion reaction on the catalyst, so that the heat generated by the combustion reaction It is supplied to the reforming reaction part as reaction heat. Background technique [0002] In recent years, as concerns about environmental issues have increased, interest and demand for clean fuels fueled by hydrogen hav...

AI Technical Summary

Problems solved by technology

However, this methanol reformer has disadvantages that the size of the reactor as a whole is large, that the combustion catalyst does not completely contact the side of the reforming catalyst, and that the combustion catalyst is not filled in one tube but dispersedly filled in multiple places. , making it difficult to efficiently supply heat to the reformer

However, this small methanol steam reforming device has the following disadvantages: it has a relatively low output power of about 200 mW, and in order to maintain the reaction temperature, a large amount of fuel, that is, methanol, is put into the burner, so that the overall thermal efficiency is very low. 5 to 10%
