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. 171.-. (canceled)72. A process for the removal of mercury from a mercury-containing hydrocarbon fluid feed , the process comprising the steps of: {'br': None, 'sup': +', 'x+', 'y−', '(nx−my), 'sub': n', 'm, '[Q][(M)(L)]'}, '(i) contacting the mercury-containing hydrocarbon fluid feed with a metallate salt immobilised on a solid support material, where the metallate salt has the formula{'sup': 'x+', 'claim-text': [{'sup': 'y−', 'each L independently represents a ligand having a charge of y−;'}, 'n is 1, 2 or 3;', 'm is 2, 3, 4, 5, 6, 7 or 8;', 'x is 2, 3, 4, 5 or 6;', 'y is 0, 1, 2 or 3,', '(nx−my) is a negative number, and', {'sup': '+', '[Q] represents one or more inorganic cations having a total charge of (my−nx); and'}], 'wherein: each M independently represents one or more metal cations selected from transition metal cations having a charge of x+;'}(ii) separating from the ionic liquid a hydrocarbon fluid product having a reduced mercury content compared to the mercury-containing fluid feed.73.
