TECHNICAL FIELD

[0001] The utility model belongs to the field of purification equipment, in particular to a kind of methanol hydrogen gas purification combination device. BACKGROUND

[0002] Methanol hydrogen gas purification equipment is a kind of professional device for purifying the gas generated by methanol hydrogen reaction.In the process of methanol hydrogen production, the gas generated by methanol reforming and other reactions is not pure hydrogen, but a mixture containing hydrogen, carbon monoxide, carbon dioxide and a small amount of other impurities. Currently, some methanol hydrogen gas purification equipment uses a single purification structure, which has certain limitations. On the one hand, if only a single adsorption purification is relied on, the selectivity of the adsorbent to impurities is limited. For example, although common molecular sieve adsorbent can adsorb some impurities such as carbon dioxide and water vapor, its adsorption effect on carbon monoxide, a small molecule impurity, especially at low concentration, is poor. This is because the carbon monoxide molecule is small and has relatively weak adsorption with the adsorbent. The conventional solution is to increase the amount of adsorbent or replace the adsorbent with slightly stronger adsorption capacity for carbon monoxide. However, this approach has drawbacks. Increasing the amount of adsorbent increases equipment costs, and frequent replacement of adsorbent not only complicates the operation, but also affects production continuity due to downtime for replacement.
