Problems solved by technology

[0016] The existing preparation methods usually only do reforming once, and then directly discharge or burn the residual gas. Since the residual gas contains harmful gases, direct discharge will seriously affect the environment and people's health
Through direct combustion, resources will be wasted and conversion rate will be reduced

Embodiment 1

[0066] see figure 1 , the present invention discloses a methanol steam reforming hydrogen production equipment, the hydrogen production equipment includes: a liquid storage container 10, a main hydrogen production equipment 20, one or more sub-hydrogen production equipment 30.

[0067] The main hydrogen production equipment 20 includes: a heat exchanger, a gasification chamber, a reforming chamber, and a separation chamber; the liquid storage container, heat exchanger, vaporization chamber, reforming chamber, and separation chamber are connected in sequence through pipelines.

[0068] The methanol and water in the liquid storage container 10 are transported to the heat exchanger through the conveying device for heat exchange, and then enter the vaporization chamber for vaporization after heat exchange. The vaporized methanol vapor and water vapor enter the reforming chamber, where a catalyst is installed, and the temperature in the reforming chamber is 280°-409°.

Abstract

The invention reveals an apparatus and a method for hydrogen production through methanol steam reforming. The apparatus comprises a liquid reservoir vessel, a main hydrogen production device and one or more sub hydrogen production devices, wherein the main hydrogen production device carries out heat exchanging, vaporization, reforming and separation to obtain hydrogen and conveys discharged residual gas into one sub hydrogen production device, and the sub hydrogen production devices receive residual gas (which includes useful gas that does not fully react) discharged by the main hydrogen production device or / and themselves or / and other sub hydrogen production devices and use the residual gas for continued preparation of hydrogen. According to the apparatus and the method for hydrogen production through methanol steam reforming in the invention, the residual gas produced by the main hydrogen production device is subjected to one or more reforming, so residual gas directly discharged is reduced, pollution to the environment is reduced, and the conversion rate of hydrogen is improved.

Description

technical field [0001] The invention belongs to the technical field of hydrogen preparation, and relates to a hydrogen production equipment, in particular to a methanol steam reforming hydrogen production equipment; at the same time, the invention also relates to a methanol steam reforming hydrogen production method. Background technique [0002] Among the many new energy sources, hydrogen energy will become the most ideal energy source in the 21st century. This is because, in the case of burning the same weight of coal, gasoline and hydrogen, hydrogen produces the most energy, and the product of its combustion is water, without ash and waste gas, and will not pollute the environment; while the combustion of coal and oil produces These are carbon dioxide and sulfur dioxide, which produce the greenhouse effect and acid rain, respectively. The reserves of coal and oil are limited, while hydrogen is mainly stored in water, and the only product after combustion is water, which ...
