Abstract: Method for preparation of an adsorbent that comprises successive shaping stages by co-granulation of a faujasite-type zeolite powder A, with a powder B that consists of alumina, whereby the ratio per unit of mass of the powder A in the mixture of powders A and B is between 10 and 70%, for treatment under water vapor and drying.The invention also relates to a process for adsorption of organic contaminants that contain at least one heteroatom and that are present in an olefinic feedstock that comprises at least 50% by volume of hydrocarbons, whereby this process comprises the stage for bringing the olefinic feedstock into contact with the adsorbent that is obtained by the preparation method according to the invention.

Abstract translation: 通过将八面沸石型沸石粉末A与由氧化铝组成的粉末B共同造粒而形成连续成型阶段的吸附剂的制造方法，由此粉末A的混合物中的粉末A的单位质量比 B为10〜70％，用于水蒸汽干燥处理。 本发明还涉及一种吸附含有至少一个杂原子且存在于包含至少50体积％的烃的烯烃原料中的有机污染物的方法，由此该方法包括使烯烃原料接触的阶段 与通过根据本发明的制备方法获得的吸附剂。
