Abstract: The present invention relates to a low-temperature additive for fuel oils having a sulfur content of less than 50 ppm, comprising i) at least one oil-soluble amide-ammonium salt of a polycarboxylic acid with a mono- and/or dialkylamine (A) and ii) 5-100% by weight, based on the amount of amide-ammonium salt (A), of an oil-soluble amine (B), and iii) 0.1 to 10 parts by weight, based on the amount of amide-ammonium salt (A), of a resin formed from at least one aromatic compound bearing an alkyl radical and an aldehyde and/or ketone (D).

Abstract: Utilization of nitrogen oxides contained in the ambient air including a system and a method with which the nitrogen oxides can be utilized for the production of liquid or solid chemicals.

Abstract: A method for determination of an effective machine use of a machine tool, as well as a machine tool that is configured for this purpose. The machine tool has multiple machine axes in order to move a workpiece and/or a tool. A rotary drive drives the workpiece or the tool in order to remove material. A control unit of the machine tool determines a use duration characteristic parameter (T) and an output power characteristic parameter (L) and determines therefrom a machine use characteristic parameter (M). The use duration characteristic parameter (T) describes a duration during which the workpiece is machined by the tool. The output power characteristic parameter (L) describes the applied or required power in order to effect the material removal. The machine use characteristic parameter (M) is determined by the control unit, such that it can be transmitted to an external unit for further evaluation or processing.

Abstract: A method for purifying the exhaust gas generated by an internal combustion engine, wherein the exhaust gas generated by the internal combustion engine is conducted through an exhaust gas path in which at least one adsorption element is arranged, to which pollutants contained in the exhaust gas at least partly bind, and in which the at least one adsorption element is regenerated by at least partial desorption of the bound pollutants, and pollutants desorbed from the at least one adsorption element during the desorption process are stored in at least one storage unit.

Abstract: Utilization of nitrogen oxides contained in the ambient air including a system and a method with which the nitrogen oxides can be utilized for the production of liquid or solid chemicals.

Abstract: Nitrogen oxides formed in combustion engines are recycled such that the nitrogen oxides can be utilized for producing liquid or solid chemicals. The nitrogen oxides are recycled by a method including an adsorber material adsorbing nitrogen oxides from an exhaust-gas stream of the combustion engine, removing the adsorber material laden with nitrogen oxides, desorbing the adsorbed nitrogen oxides from the adsorber material, and converting the nitrogen oxides desorbed from the adsorber material into liquid or solid nitrogen-containing compounds.
