A novel process for treating pickling acid residue and recovering sulfates and nickel therefrom has been developed. By lowering the pH of a magnesium compound slurry to 4-5.5 with sulfuric acid containing pickling acid residue in the presence of ammonium sulfate, both magnesium sulfate and nickel sulfate are solubilized. Magnesium sulfate and nickel sulfate solution is separated from the solids by filtration and an iron hydroxide and chromium hydroxide residue is obtained as a precipitate. Magnesium sulfate and nickel sulfate are then separated from the solution.

Method for treating pickling acid residue

The purpose of the present invention is to provide organometallic salt compositions that are useful as lubricant additives and/or in lubricant additive compositions to reduce friction and wear, and also have improved solubility in all four types of hydrocarbon base oils (Groups I-IV) at a variety of concentrations and under a variety of conditions. The organometallic salt composition is derived from at least one long chain monocarboxylic acid and a single metal in combination with at least one short or medium branched-chain monocarboxylic acid. The compositions are particularly useful in combination with activated complexes comprising a first metal component, a second metal component and particles comprising the first metal component.

Organometallic salt composition, a method for its preparation and a lubricant additive composition

A novel process for treating and recovering valuable metals and other components from pickling acid residue (PAR) has been developed. The metals and other components are recovered by neutralizing the pickling acid residue using a magnesium compound or a mixture of magnesium compounds, and separating components of the resulting mixture (metals and sulfates) into products that can be reused, such as magnesium sulfate, nickel sulfate, iron and chromium phosphate, or various metal hydroxides or oxides.

Process for recovering components from pickling acid residue

The present invention describes a composition characterized in that the composition comprises a first metal component and particles including a second metal component. Furthermore the present invention describes a lubricant additive composition, a lubricant composition and a grease composition comprising the present composition.

Composition

A method for the recovery of a metal from a liquid medium containing the metal I solution or in finely divided insoluble from comprises contacting the medium with a functionalized polymer fiber capable of binding the metal and recovering the metal from the fiber. The polymer fiber is suitably a polyolefin, a fluorinated polyethylene, cellulose or viscose, which is functionalized by the radiation grafting of at least one monomer. The method is particularly suitable for the recovery of platinum group metals from process residues.

Precious metal scavenging from a liquid medium with a functionalised polymer fiber

A fibrous catalyst comprises at least one transition metal anchored to a polymer fiber having a plurality of grafted units grafted to a polymer backbone. The polymer backbone may be a polyolefin, a fluorinated polyethylene, cellulose or viscose. The grafted units comprise a salt of a carboxylic acid, which in a preferred embodiment is a sodium salt of acrylic acid. The catalysts are particularly suitable for scavenging oxygen from sealed packages or containers and may further comprise a chemical indicator for the presence or absence of oxygen.

Oxygen scavenging

A process for the production of a graft copolymer comprises reacting an irradiated polymer in a reaction mixture comprising a first phase and a second phase. The first phase comprises a source of at least one non-water soluble monomer and the second phase comprises water and optionally, a water miscible organic solvent. The first and second phases are substantially immiscible and non-emusifiel. A high degree on monomer conversion is achieved.

Graft copolymers

The invention concerns a polymer support of with highly accessible reactive groups onto which desired functional groups or metals can be attached, the polymer support comprising a polymer material which is grafted with reactive groups suitable to bind the functional group or metal to be loaded. The polymer material is encompassed in a bag made of meshed fabric which is tight enough to essentially prevent the escape of the polymer material from the bag. Furthermore, the invention relates to a functionalized polymer support and to a process for its preparation. The invention also concerns a product useful as an intermediate in the preparation of the polymer support.

Polymer supports comprising highly reactive grafted polyolefin

The object of the present invention is a process of preparation of a graft copolymer obtained by pre-irradiation grafting of vinyl monomers onto polyolefins or fluorinated polyethylenes, in particular, of grafting acrylic or methacrylic acid onto polyethylene and/or polypropylene and subsequently loading a metal, such as a transition metal on the graft copolymer obtained. Such metal-loaded graft copolymers find use, especially as catalysts, e.g. for hydrogenation reactions.
