摘要:
A method and apparatus for determining a concentration of aerosol particles in a carrier gas. The method comprises providing an aerosol having aerosol particles in a carrier gas comprising at least one condensable component; introducing at least part of the aerosol into a chamber of a pressure-rated vessel, wherein the chamber is delimited by at least one wall adjoining the chamber and set to a temperature which is above a saturation temperature of the at least one condensable component; subsequently removing part of the aerosol from the chamber, as a result of which a decrease in pressure in the chamber occurs, as a result of which the at least one condensable component condenses at least partly on the aerosol particles; and determining a concentration of aerosol particles in the carrier gas during removal of the part of the aerosol from the chamber.

Direct thermal decomposition of hydrocarbons into solid carbon and hydrogen is performed by a process and a device. The process comprises preheating a hydrocarbon gas stream to a temperature between 500° C. and 700° C. and injecting the pre-heated hydrocarbon gas stream into the reactor pool of a liquid metal reactor containing a liquid media; forming a multi-phase flow with a hydrocarbon gas comprising hydrogen and solid carbon at a temperature between 900° C. and 1200° C.; forming a carbon layer on the free surface of the liquid media made up of solid carbon particles which are then displaced into at least one carbon extraction system and at least one recipient for collecting them; and, at the same time, the gas comprising hydrogen leaves the reactor pool through a porous rigid section, being collected at a gas outlet collector from where the gas comprising hydrogen finally leaves the liquid metal reactor.

摘要:
The subject of the present invention is a device for the in situ analysis of batteries by means of X-ray, synchrotron or another radiation. The device has a sample support, which is realized as a sample wheel rotatably mounted about the centre axis. A plurality of sample holders, the centre points of which are placed on a common circular line about the centre point of the sample support, are arranged on the sample support, wherein each sample holder can be repeatedly opened and closed individually by an arrestable cover. Each sample holder has in its interior a cavity which receives the battery, which is to be examined, in a manner ideal in shape with regard to circumference, wherein the cover and the cavity have an opening for the passage of the beam. A spring, engaging in the edge region of the battery, presses the battery against the cover, wherein the spring and the edge region of the cover are embodied so as to be electrically conducting but insulated with respect to one another. There are directed from each sample holder an electrically conductive connection from the edge region of the cover, and an electrically conductive connection from the spring onto the face of the sample support facing away from the cover and into the vicinity of its centre point. There, the lines of all sample holders are combined to form a line bundle or a plug connector.
