| 摘要 |
The instant invention is directed to a method for reducing the amount of sulfur in hydrocarbon streams comprising the steps of: (a) contacting a hydrocarbon stream comprising hydrocarbons and sulfur compounds with an adsorbent selective for adsorption of said sulfur compounds, under adsorption conditions capable of retaining said sulfur compounds on said adsorbent and obtaining an adsorption effluent comprising a desulfurized hydrocarbon stream, (b) collecting said desulfurized hydrocarbon stream, (c) desorbing said sulfur compounds from said adsorbent by passing a desorbent through said adsorbent under desorption conditions to obtain a desorption effluent comprising sulfur compounds and said desorbent, (d) treating said desorption effluent to remove said sulfur compounds from said desorption effluent and collecting a desulfurized desorbent effluent comprising desorbent.
