Process for selective capture of arsenic in gasolines rich in sulphur and olefins
摘要：
A process for capturing organometallic impurities comprising at least one of a heavy metal, silicon, phosphorus, and arsenic, contained in a hydrocarbon feed comprising contacting the feed with a capture mass comprising at least one of iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), lead (Pb) and zinc (Zn) deposited on a porous support at least one of aluminas, silica, silica-aluminas, and titanium, or magnesium oxides used alone or as a mixture with alumina or silica-alumina, the metallic element being in the sulphide form with a degree of sulphurization of at least 60%, and in which the feed to be treated is a catalytically cracked gasoline containing 5% to 60% by weight of olefins, 50 ppm to 6000 ppm by weight of sulphur and traces of arsenic in amounts in the range 10 ppb to 1000 ppb by weight.
摘要（中）：

一种用于捕获包含在烃进料中的包含重金属，硅，磷和砷中的至少一种的有机金属杂质的方法，包括使进料与含有铁（Fe），钴（Co）， 沉积在多孔载体上的氧化铝，二氧化硅，二氧化硅 - 氧化铝和钛中的至少一种的镍（Ni），铜（Cu），铅（Pb）和锌（Zn），或单独使用或与氧化铝的混合物 或二氧化硅 - 氧化铝，金属元素为硫化物形式，其硫化程度至少为60％，其中待处理的进料是含有5重量％至60重量％烯烃的催化裂化汽油，50ppm 至6000ppm（重量）的硫和痕量的砷，其重量在10ppb至1000ppb的范围内。
