  • Process for removing metals from hydrocarbons
    Patent number: 10138432
    Abstract: Mercury is removed from a mercury-containing hydrocarbon fluid feed by utilizing ionic liquids. The mercury-containing hydrocarbon fluid feed is contacted with a metallate salt immobilized on a solid support material. A hydrocarbon fluid product having a reduced mercury content compared to the mercury-containing fluid feed is separated from the ionic liquid.
