PROCESS FOR PRODUCING HIGH PURITY HYDROGEN BY CATALYTIC REFORMING OF METHANOL

摘要

Process for the production of hydrogen by steam reforming of methanol, in which water and methanol are reacted (4) at a relatively high pressure over a suitable catalyst, the gases originating from the reaction are, after condensation (7) at a relatively high pressure, brought into contact (10) with an adsorption agent so as to adsorb the byproducts of the reaction and to release a hydrogen-rich gas (11) and the byproducts are periodically desorbed at a relatively low pressure and are recycled to the steam-reforming reactor (4) at the same time as a fraction of the hydrogen present in the adsorption zone (10), after they have undergone a recompression (13) and a treatment (14) for the removal of at least a portion of the carbon dioxide at a relatively high pressure. …IMAGE…
