Patent

CA 2416239

A process to regenerate iron-based hydrogen sulfide sorbents using steam. The steam is preferably mixed with hydrogen-containing gas and/or an inert gas, such as nitrogen. In a preferred embodiemtn, the sorbent is first exposed to the steam and then exposed to a hydrogen-containing gas at regeneration conditions.

L'invention concerne un procédé de régénération de sorbants de sulfure d'hydrogène à base de fer par utilisation de vapeur d'eau. La vapeur d'eau est, de préférence, mélangée avec un gaz contenant de l'hydrogène et/ou un gaz inerte, tel que l'azote. Dans un mode de réalisation préféré, le sorbant est d'abord exposé à la vapeur d'eau et ensuite exposé à un gaz contenant de l'hydrogène dans des conditions de régénération.
