Publication number: 20230399720Abstract: The present invention relates to the recovery and purification of lithium from lithium containing sources, like lithium ion battery materials, using ion exchange. A lithium salt containing solution is passed through an acid cation exchange resin, and a lithium raffinate and a mixture of other elements such as metals like nickel, cobalt and manganese, are recovered as products. The lithium raffinate can then be processed into other lithium products such as lithium carbonate and lithium hydroxide.Type: ApplicationFiled: November 9, 2021Publication date: December 14, 2023Inventors: Paula Kivelä, Peik Ekman, Pasi Kauppinen, Kenneth Ekman, Ville Yrjänä

Patent number: 11254585Abstract: 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.Type: GrantFiled: December 18, 2020Date of Patent: February 22, 2022Assignee: CrisolteQ LtdInventors: Kenneth Ekman, Peik Ekman, Elina Lappalainen

Patent number: 10618865Abstract: 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.Type: GrantFiled: June 27, 2016Date of Patent: April 14, 2020Assignee: Ab Nanol Technologies OyInventors: Aubrey Burrows, Kenneth Ekman, Sophia Von Haartman, Samuli Lempiäinen, Johan Von Knorring

Patent number: 8282705Abstract: A method is provided for recovering metals from a spent catalyst composition containing an organic contaminant and catalytically active metals on a catalyst support. The metals are leached from the spent catalyst composition by adding under stirring an ionic liquid. The ionic liquid containing the leached metals is separated from the organic contaminant and the catalyst support by adding under stirring an anti-solvent. After removing the organic contaminant and the catalyst support, the leached metals are separated from the ionic liquid for example by selective precipitation, ion exchange, solvent extraction, electrodeposition, chromatographic, or pyrometallurgical methods.Type: GrantFiled: June 18, 2008Date of Patent: October 9, 2012Assignees: Crisolteq Oy, OMG Kokkla Chemicals OyInventors: Kenneth Ekman, Manne Carla, Mats Sundell, Virginie Suhonen, Joni Hautojärvi

Patent number: 5960355Abstract: The present invention teaches a method, system, terminals and service node for geographically positioning a first mobile radio terminal (MS1) within a radio network (100) comprising unsynchronised radio base stations by using a plurality of second fixed radio terminals (MS2) whereby the positions of the radio base stations and the second fixed radio terminals are known. First and second radio terminals (MS1,MS2) measure the relative receive times between the timing signals downlink (113-118) received from at least three radio base stations (BS1,BS2,BS3) and the second fixed radio terminals (MS2)send them to a service node (107) in the network (100) using them for calculating the transmission time offsets of the timing signals downlink.Type: GrantFiled: February 10, 1997Date of Patent: September 28, 1999Assignee: Telefonaktiebolaget LM EricssonInventors: Kenneth Ekman, Anders Hedlund, Rikard Lundqvist, Walter Ghisler
