Abstract
Removal of organic sulfur compounds, especially aromatic sulfur compounds from an FCC feedstock with minimal adsorption of aromatic hydrocarbons is achieved using a zeolite X exchanged with alkali or alkaline earth cations. KX is an especially effective adsorbent. Where the KX is loaded with a group VIII metal, particular palladium or platinum, the adsorbent is effectively regenerated by treatment with hydrogen at elevated temperatures.
