The present inventions is concerned with an apparatus and a method of improving the accuracy of coating a ceramic or metallic honeycomb body, which can usually be used as a catalyst in automotive exhaust mitigation. The invention achieves to directly test whether the coating slurry in the coating chamber is ready to be submitted to the monolith or needs to be replaced before coating the monolith.


The present invention relates to a process for preparing hydridocarbonyltris(triphenylphosphine)rhodium(l), RhH(CO)(PPh3)3, also referred to hereinafter as Rh-hydrido. An alcoholic suspension of triphenylphosphine is stirred with an Rh(III) chloride precursor at elevated temperature. The Rh(III) chloride precursor used may be rhodium(III) chloride hydrate RhCl3*xH2O or rhodium(III) chloride solution H3[RhCl6]*(H2O)n. After cooling, alcoholic alkali metal hydroxide solution is added, and the mixture is stirred for a few hours. Finally, sparging is effected with CO gas and the Rh-hydrido formed is removed. Rh-hydrido can be prepared by this process on the industrial scale in high yields and with very good quality.


The purpose of the present invention is to provide an oxidation catalyst for exhaust gas purification having high durability and a method for producing the catalyst. The purpose is achieved by an oxidation catalyst for exhaust gas purification containing a refractory inorganic oxide, -zeolite, a catalyst component and a metal component, which are supported on the refractory inorganic oxide and -zeolite, all of said components being supported on a three dimensional structure. The catalyst component is platinum, or platinum and palladium, and the metal component is calcium, in an amount of 0.001 to 0.12 mol per 1L of a catalyst in Ca conversion.

The invention concerns a process for the separation of cobalt from lithium present in a charge comprising lithium-ion batteries or related products, comprising the steps of: smelting the charge using a bath furnace equipped with a submerged air-fed plasma torch for injecting plasma gas into the melt; defining and maintaining a bath redox potential where cobalt is reduced to the metallic state and reporting to an alloy phase, and whereby lithium is oxidized as Li2O and reporting to the slag phase; decanting and separating the phases. It is characterized in that the reduction and oxidizing steps are performed simultaneously. A suitably low cobalt concentration is obtained in the slag.

The invention relates to a method for the cost-effective and environmentally friendly production of alkyl indium sesquichloride in high yield and with high selectivity and purity. The alkyl indium sesquichloride produced according to the invention is particularly suitable, also as a result of the high purity and yield, for the production, on demand, of indium-containing precursors in high yield and with high selectivity and purity. As a result of the high purity, the indium-containing precursors that can be produced are particularly suitable for metal organic chemical vapour deposition (MOCVD) or metal organic vapour phase epitaxy (MOVPE). The novel method according to the invention is characterised by the improved execution of the method, in particular a rapid process control. Owing to targeted and extensive use of raw materials that are cost-effective and have a low environmental impact, the method is also suitable for use on an industrial scale.

METGROW\ will address and solve bottlenecks in the European raw materials supply by developing innovative metallurgical technologies for unlocking the use of potential domestic raw materials. The METGROW\ consortium has received an EIP RM Commitment status. The consortium is supported by internationally respected research institutes and universities. Many of the partners (9) are members of EIT KIC Raw Materials consortium as well. The value chain and business models for metal recovery from low grade ores and wastes are carefully looked after. Within this project, both primary and secondary materials are studied as potential metal resources. Economically important nickel-cobalt deposits and low grade polymetallic wastes, iron containing sludges (goethite, jarosite etc.) which are currently not yet being exploited due to technical bottlenecks, are in focus. Concurrently, METGROW\ targets innovative hydrometallurgical processes to extract important metals including Ni, Cu, Zn, Co, In, Ga, Ge from low grade ores in a cost-effective way. In addition a toolbox for metallurgical system is created in the project using new methods and combinations. The unused potential of metal containing fine grained industrial residues are evaluated, while hybrid and flexible hydrometallurgical processes and treatment methods of fines are developed for both materials. Training and education of new professionals are facilitated within the METGROW\ project. The knowledge of raw materials and sustainable technologies will attract new talents in the field who can flexibly change fields from treatment of secondary to primary resources, which also smoothens the economic ups and downs in the primary sector.
