The catalyst process for hydrogen production from methanol cracking uses methanol and desalted water as raw materials. At 220 ~ 280 °C, the catalytic conversion on the special catalyst is mainly composed of hydrogen and carbon dioxide conversion gas. The following methanol cracking hydrogen production catalyst manufacturer-Suzhou Jiarui gas is a detailed introduction to the process of methanol cracking hydrogen production catalyst :
Methanol and desalted water are mixed in a certain proportion and preheated by the heat exchanger before being sent to the vaporization tower. The vaporized water methanol vapor is overheated by the boiler heater and then enters the converter for catalytic cracking and conversion reaction in the catalyst bed. The output conversion gas contains about 74 % hydrogen and 24 % carbon dioxide. After heat exchange, cooling and condensation, it enters the water washing absorption tower. The unconverted methanol and water are collected from the tower kettle for recycling, and the top gas is sent to the pressure swing adsorption device for purification.
According to the different requirements of product gas purity and trace impurity components, the purity can reach 99.9 ~ 99.999 % by using four or more towers process. A pressure swing adsorption device with a processing capacity of 1500 Nm3 / h conversion gas and a purity of 99.9 % is designed, and its hydrogen recovery rate can reach more than 90 %.
Carbon dioxide in converted gas can be purified to food grade by pressure swing adsorption device, which is used in beverage and alcohol industry. This can greatly reduce the production cost. After the carbon dioxide is separated by the pressure swing adsorption device, the hydrogen-rich conversion gas is pressurized and sent to the pressure swing adsorption device for purification.
The above is sorted out and released by Suzhou Jiarui Gas, a methanol cracking hydrogen production catalyst manufacturer.
