The present invention relates to a process for dissolving metals in perhalide containing ionic liquids, and to the extraction of metals from mineral ores; the remediation of materials contaminated with heavy, toxic or radioactive metals; and to the removal of heavy and toxic metals from hydrocarbon streams.

Ionic liquid solvents of perhalide type for metals and metal compounds

This invention relates to a process for removing metals, particularly mercury, from hydrocarbon streams by use of an ionic liquid, where in the metal-containing hydrocarbon stream is contacted with an ionic liquid to produce a product hydrocarbon stream having reduced mercury content.

Process for removing metals from hydrocarbons

This invention provides a process for removing mercury, from a mercury-containing hydrocarbon fluid. More specifically, the invention relates to a process for the removal of mercury from a mercury-containing hydrocarbon fluid feed comprising the steps of: (i) contacting the mercury-containing hydrocarbon fluid feed with a metal perhalide having the following formula: [M][X]wherein: [M]represents one or more metal cations wherein the metal has an atomic number greater than 36; an atomic radius of at least 50 pm and a 1st ionization energy of less than 750 kJmol; [X]represents one or more perhalide anions; and (ii) obtaining a hydrocarbon fluid product having a reduced mercury content compared to mercury-containing hydrocarbon fluid feed.

Process for removing heavy metals from hydrocarbons

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.

The present invention relates to a process for the removal of mercury from a mercury-containing hydrocarbon fluid feed using specifically selected ionic liquids comprising, contacting the mercury-containing hydrocarbon fluid feed with an ionic liquid having the formula [Cat][M][X] and separating from the ionic liquid a hydrocarbon fluid product having a reduced mercury content compared to the mercury-containing fluid feed.

A process is described for the preparation of water-soluble cellulose hydrolysis products The process comprises admixing cellulose with an ionic liquid capable of solvating or dissolving at least some of the cellulose, said ionic liquid being a compound comprised solely of cations and anions and which exists in a liquid state at a temperature at or below 150&#xb0; C., and in which the anions are selected from sulfate, hydrogen sulfate and nitrate; and treating the resulting solvate or solution with an acid in the presence of water, said acid having a pKa in water of less than 2 at 25&#xb0; C.

Conversion method

A process is described for the preparation of water-soluble cellulose hydrolysis products, which comprises admixing cellulose with an ionic liquid capable of solvating or dissolving at least some of the cellulose, said ionic liquid being a compound comprised solely of cations and anions and which exists in a liquid state at a temperature at or below 150&#xb0; C., the cations in said ionic liquid having the general formula (I), in which Z represents a nitrogen or phosphorus atom, Rrepresents a methyl or ethyl group, each of Rand R, which may be the same or different, is selected from Calkyl, optionally-substituted benzyl, optionally-substituted phenyl, and Ccycloalkyl, and Rrepresents Calkyl, optionally-substituted benzyl, optionally-substituted phenyl or Ccyclohexyl; in which the optional substituents on a benzyl or phenyl ring are one, two or three substituents selected from Calkyl or alkoxy groups, halogen atoms and nitro groups; and treating the resulting solvate or solution with an acid in the presence of water, said acid having a pKa in water of less than 2 at 25&#xb0; C.

A method for breaking an emulsion of an ionic liquid which is a salt that is in the liquid state at a temperature below 1500 C, and an oil, comprising the steps of (a) irradiating the emulsion with microwave radiation; (b) separating the emulsion into an ionic liquid phase and an oil phase; and (c) recovering at least one of the phases.
