Luoyang 2*200Nm3/h Hydrogen Production From Methanol

Technology Application

Using methanol as raw material, crude hydrogen (mainly CO2, H2, and trace CO, CH4) is produced by steam cracking process, and then purified by pressure swing adsorption technology to obtain hydrogen with purity meeting the requirements of users.
The raw methanol and raw desalted water are premixed at a certain ratio, pressurized by metering pump, preheated, gasified and superheated, and then enter the reactor. Under the action of catalyst, the reaction is carried out to generate crude hydrogen. After heat exchange, the heat is recovered, cooled, and then enter the pressure swing adsorption device for final purification.

Process Principles for pressure swing adsorption

Adsorption: a phenomena and process is that when the two material of different physical phases contact, the material molecules with low density enrich in the surface of which with high density. Adsorbing material (usually a porous solid density is relatively large ) is known as the adsorbent, adsorbed material (usually a gas density is relatively small) is called as adsorbate. According to the nature of the different adsorption, it can be divided into four categories, namely: the chemical adsorption, activated adsorption, capillary condensation and physical adsorption.

Physical adsorption is to rely on the adsorption of molecular force between the agent and the adsorbate molecules (including Van der Waals' force and electromagnetic force) .Its characteristics are: no chemical reaction in the process of adsorption, adsorption process was quick, and this adsorption is completely reversible.
