The present development is a reactor system for the production of nanostructures. The reactor system comprises a conical reactor body designed to maintain an upwardly directed vertical plasma flame and hydrocarbon flame. The reactor system further includes a metal powder feed that feeds into the plasma flame, a cyclone and a dust removal unit. The system is designed to produce up to 100 grams of metal oxide nanomaterials per minute.

A reaction chamber for a chemical reactor comprises a casing (100) of the reaction chamber, a floor (200) of the reaction chamber having an opening (300) located in the floor, an agitator shaft (400) located in the chamber and having at least one agitator element (500), connected thereto, wherein the agitator shaft (400), seen in the longitudinal direction, has a beginning (600) and an end (700). In the opening (300) of the floor (200) a removable sleeve (800) is provided, which projects out of the reaction chamber. The sleeve (800) is arranged in alignment with the axis of rotation of the agitator shaft (400). The internal diameter of the sleeve (800) is greater than the diameter of the agitator shaft (400) and the agitator shaft (400), at the beginning (600) thereof and/or at the end (700) thereof, is adapted to absorb reversibly a torque provided by means of a further shaft and/or to transmit a torque to a further shaft. Using such a reaction chamber, it is possible to build up modular chemical reactors having decreased backmixing.

The invention relates to a method and an assembly for recovering magnesium ammonium phosphate from slurry supplied to a reaction container (10) in which an aerobic milieu that is alkaline as a result of CO.sub.2-stripping is present and in which the slurry is guided in a circuit with the aid of ventilation. Cationic magnesium, such as magnesium chloride, is added to the slurry, and magnesium ammonium phosphate crystals which are crystallized out of the slurry are removed via a removal device (30) provided in the base region of the reaction container. The slurry is supplied from the first reaction container (10) to a second reaction container (12) via a first line (14), wherein an anaerobic milieu is set in the second reaction container in order to redissolve the phosphate, and MAP crystals crystallized in the second reaction container are supplied to the first reaction container.

A device for the descending flow of a hydrocarbon-containing liquid containing solid particles at the bottom of an item of equipment (1) and a process for the conversion of hydrocarbon-containing feedstocks implementing said device.

Systems and methods include a computer-implemented method can be used to make milling tools from new wurtzite boron nitride (w-BN) superhard material. An ultra-high-pressure, high-temperature operation is performed on pure w-BN powder to synthesize w-BN and cubic boron nitride (c-BN) compact having a first size greater than particles of the pure w-BN powder. The ultra-high-pressure, high-temperature operation includes pressurizing the w-BN powder to a pressure of approximately 20 Gigapascal, heating the w-BN powder at a heating rate of 100 C./minute and cooling the w-BN powder at a cooling rate of 50 C./minute. The compact is cut to a second size smaller than the first size using laser cutting tools. The cut compact is turbulently mixed with additives in a mixer under vacuum. The cut compact mixed with the additives is thermally sprayed onto a tool substrate to form the tool.
