Abstract: Waste feed material, such as Automotive Shredder Residue (ASR) feed material, that includes hydrocarbon materials and inorganic materials is processed using photolysis. A reactor includes a chamber that receives waste feed material including a majority of hydrocarbon material after the substantial removal of inorganic material including metals and minerals. A photonic illumination or photolysis module irradiates the feed material within the chamber of the reactor to decompose the hydrocarbon or hydrocarbon materials within the waste feed material into gases and/or carbonaceous solids. A mechanical movement unit moves the waste feed material within the chamber of the reactor to facilitate exposure of different portions of the feed material to irradiation within the chamber during system operation. A pre-treatment module substantially removes the contained metals and minerals in the waste material from the hydrocarbon material fed to the reactor.

Abstract: During voltammetric analysis of liquids, the indicator electrode must be frequently changed in order to prevent memory effects and resultant changes to basic conditions during measurement. In order to be able to change the indicator electrodes simply, a plurality of indicator electrodes are arranged on a common carrier. For accommodation of the liquid (2) to be analysed, a vessel (1) is provided and the carrier (5) is mounted to move in relation to this vessel (1) in such a way that one of the indicator electrodes (6) can be selectively brought into the area intended for the liquid. The reference electrode (8) necessary for the measurement is arranged in the vessel (1) and likewise connected with the measuring device (20). With that, changing of the selected electrode (6) ensues by moving the carrier (5) relative to said vessel (1).
