Abstract

[0002] Methanol hydrogen production is a technical route for hydrogen production. China is the world's largest methanol producer, with 60% of the world's methanol production capacity. Methanol is abundant in source, low in cost, and easy to store and transport as a liquid at room temperature and pressure. Compared with other hydrogen production methods such as industrial hydrogen production, methanol hydrogen production has lower energy consumption and cost. Methanol reformer is a device that uses catalytic reforming technology to convert liquid methanol-water solution at room temperature into hydrogen-rich gas. The output gas of this device is mainly hydrogen, and may also contain other components such as carbon dioxide and carbon monoxide. If high-purity hydrogen is required, a special purification device can be installed at the tail end.

After heat exchange, the gas needs to be condensed for separation and purification. The traditional gas gathering pipe needs to transport the gas to the inside of the condensation equipment, which increases the cost of hydrogen production. In addition, there are gaps in the connections between the pipelines, which leads to gas leakage. Utility Model Content
