Werkwijze voor het ontzwavelen van brandstofgasstromen.

摘要

The invention relates to a method for the removal of organosulphur compounds from fuel gas streams in that the gas stream is brought into contact with an adsorbent, and wherein the adsorbent is a support material on which metal salts have been deposited. The invention also relates to a method for depositing metal salts on a support material, comprising mixing the desired amount of metal salt of approximately 0.2 - 50 % (m/m) (based on the metal with respect to the support material) with a liquid; mixing the solution or suspension with the support material at temperatures of up to approximately 60 - 80 °C, with stirring and/or ultrasound waves; and drying the product obtained at temperatures of up to approximately 60 - 80 °C. The invention also relates to adsorbents that have been obtained or can be obtained in this way and to the use of such adsorbents for the removal of organosulphur compounds from fuel gas streams. The invention also relates to a combination of a gas filter based on this adsorbent and a (PEMFC) fuel cell.
