Embodiment Construction
[0055] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0056] Such as figure 1 with figure 2 As shown, the embodiment of the present invention provides a hydrogen production device for producing hydrogen from liquid methanol. The hydrogen production device includes:
[0057] The base shell 1 is provided with an air inlet and an air outlet;
[0058] An evaporator 2, which is arranged in the base shell 1 for converting methanol from a liquid state to a gaseous state;
[0059] Catalytic bed 3, which is set in base shell 1 and connected to evaporator 2, is used to catalyze gaseous methanol to generate reformed gas containing hydrogen; that is, liquid methanol enters catalytic bed 3 after being converted by evaporator 2 A catalytic reaction occurs in the medium to generate hydrogen and waste gas (such as CO, CO 2 Mixed gas with water vapor), hydrogen is mixed with waste gas to form reformed gas;
[0060] A purifier 4, ...

The invention provides a hydrogen preparation device used for preparing hydrogen by utilizing liquid methyl alcohol. The hydrogen preparation device comprises a base shell, an evaporator, a catalytic bed, a purifier and a burning component, wherein the evaporator is arranged in the base shell and used for converting the methyl alcohol in the base shell from a liquid state into a gas state; the catalytic bed is arranged in the base shell, communicated with the evaporator and used for causing the gaseous methyl alcohol have a catalytic reaction for generating reformed gas; the purifier is arranged in the base shell, communicated with the catalytic bed and used for purifying hydrogen from the reformed gas; the burning component is arranged in the base shell; the burning component is used for heating the cold air introduced into the base shell so as to supply heat to the catalytic bed and the evaporator and guarantee the full catalytic reaction of methyl alcohol. The hydrogen preparation device provided by the invention is low in cost, and is capable of efficiently preparing hydrogen.
Description
technical field [0001] The invention relates to the field of chemical industry, in particular to a hydrogen preparation device. Background technique [0002] Hydrogen is used frequently in industry. In the prior art, there are multiple methods for the industrial preparation of hydrogen: [0003] ①The electrolysis method electrolyzes water to obtain hydrogen and oxygen. In the chlor-alkali industry, hydrogen is also produced as a by-product when electrolyzing salt solution to produce chlorine and caustic soda. The electrolysis method can obtain pure hydrogen, but the power consumption is very high, and every 1m of hydrogen produced 3 , power consumption of 21.6 ~ 25.2MJ. [0004] ② Hydrocarbon cracking method The cracked gas obtained by this method contains a large amount of hydrogen, and the hydrogen content varies depending on the nature of the raw material and the cracking conditions. Hydrogen with a purity of 90% can be obtained by cryogenic separation of cracked gas...
