Patent number: 11434428Abstract: Coke including additives that are accumulated at the yield points or in the regions surrounded by the yield points. For homogeneous distribution, the additives are continuously dosed into the delayed coker during the filling time. The dosing can be carried out by powdery blowing with an inert gas (nitrogen) or also distributed in a slurry consisting of the reaction components and a partial flow of the coker feed (vacuum resid, pytar, decant oil or coal-tar distillates). According to an advantageous form of embodiment, the additives may optionally have a diameter of between 0.05 mm and 5 mm, preferably between 1 mm and 3 mm. Advantageously, the additives can be selected from at least one of acetylene coke, fluid coke, flexi coke, shot coke, carbon black, non-graphitisable carbons (chars), non-graphitic anthracite, silicon carbide, titanium carbide, titanium diboride or mixtures thereof.Type: GrantFiled: January 30, 2017Date of Patent: September 6, 2022Assignee: Tokai COBEX GmbHInventors: Oswin Öttinger, Heribert Walter, Martin Christ, Johann Daimer, Wilhelm Frohs, Frank Hiltmann, Rainer Schmitt

Publication number: 20150337101Abstract: Rigid polystyrene foams contain thermally treated non-graphitic anthracite coke particles. Such athermanous materials permit a more energy-efficient grinding process, wherein the ground particles are yielded in the desired platelet form and these ground particles also disperse well in a polystyrene matrix. Therefore the rigid polystyrene foams containing the anthracite coke particles have a density of less than 40 kg/m3 and a thermal conductivity of less than 40 mW/m·K which provides desired thermal insulation properties.Type: ApplicationFiled: August 5, 2015Publication date: November 26, 2015Inventors: WILHELM FROHS, WERNER HANDL

Publication number: 20140197560Abstract: A method produces carbon fiber-reinforced coke. Carbon fiber-reinforced plastic (CFRP) materials derived from components and semi-finished products are continuously fed through a top side of the drum of a delayed coker as a partial flow or as a main flow, and the CFRP materials sink through the gas phase into the still liquid phase. The carbon fibers are released through carbonization of the resin matrix and incorporated therein during the coking process. The decomposition products of the resin matrix are supplied to a material recovery process.Type: ApplicationFiled: March 14, 2014Publication date: July 17, 2014Applicant: SGL CARBON SEInventors: WILHELM FROHS, FELIX ECKSTORFF

Patent number: 7276284Abstract: A number of properties of polygranular carbon bodies can be improved by small quantities of carbon fibers being incorporated in the formulations for production of such bodies. However, it has proven difficult for carbon fibers to be introduced into the green mixture. Therefore, a high-grade coke, preferably needle coke, in accordance with the invention is used to produce the polygranular carbon bodies. This high-grade coke according to the invention contains the carbon fibers simply as a result of being produced in the delayed coker of a refinery. All the main details of the way in which a coke of this type is mixed into the green mixture correspond to the reliably managed processing of other needle cokes.Type: GrantFiled: December 18, 2003Date of Patent: October 2, 2007Assignee: SGL-Carbon AGInventor: Wilhelm Frohs
