    Abstract: The present disclosure provides a process for removing metal contaminants from a contaminated fluid stream comprising the step of contacting said fluid stream with macroporous alpha alumina to obtain a fluid stream containing less than 50 ppm of metal. The fluid stream can be selected from the group consisting of a stream of mineral acid(s) and a stream of alkylene(s); and the metal contaminant can be at least one of elemental metals and metal oxides. The process further comprises a step of obtaining spent macroporous alpha alumina and regenerating active macroporous alpha alumina therefrom by washing said spent macroporous alpha alumina with at least one purified stream selected from the group consisting of a stream of mineral acid(s) and a stream of alkylene(s).

    Abstract translation: 本公开提供了从污染的流体流中除去金属污染物的方法,包括使所述流体流与大孔α氧化铝接触以获得含有小于50ppm金属的流体流的步骤。 流体流可以选自无机酸流和亚烷基团; 并且金属污染物可以是元素金属和金属氧化物中的至少一种。 该方法还包括通过用至少一种选自下列的纯化流洗涤所述废大孔α氧化铝,从而获得用过的大孔α氧化铝并再生活性大孔α氧化铝的步骤:选自无机酸流和 亚烷基(一个或多个)。
