Patent number: 9290709Abstract: A process and device for the gasification of liquid or fine-grain solid fuel materials with the aid of oxygenous, gaseous gasification agents in a reactor is described. Liquid slag is separated on the walls of the reactor. The synthesis gas is generated in a first reaction chamber arranged in the upper part of the reactor and the feedstock is fed to the upper part. Liquid slag precipitates on its lateral walls, with free downflow and no solidification of the slag surface. The lower side has a hole with a slag drop-off edge, from which the generated synthesis gas can be withdrawn in downward direction and the liquid slag can drop off the edge. A second chamber which is delimited by a water film is located under the opening and used to keep the synthesis gas dry and cool. A third chamber is adjacent to the bottom of the second and fed with water to cool the synthesis gas.Type: GrantFiled: September 18, 2008Date of Patent: March 22, 2016Assignee: THYSSENKRUPP INDUSTRIAL SOLUTIONS AGInventors: Johannes Kowoll, Eberhard Kuske, Ralf Abraham, Max Heinritz-Adrian

Publication number: 20120197054Abstract: A process for the dehydrogenation of alkanes. In several reactors of the adiabatic, allothermal or isothermal type or combinations thereof a gaseous alkane-containing material stream is passed through a catalyst bed in continuous operating mode. The gas stream produced contains an alkene, hydrogen and a non-converted alkane. In order to achieve a constant product composition, at least one of the process parameters of temperature, pressure or steam/hydrocarbon ratio is recorded in the form of measured values at one or several points of at least one of the reactors, where at least one of the process parameters is selectively controlled and influenced such that the composition of the product gas at the outlet of one reactor remains constant throughout the operating period.Type: ApplicationFiled: July 16, 2010Publication date: August 2, 2012Applicant: THYSSENKRUPP UHDE GMBHInventors: Helmut Gehrke, Rolf Schwass, Max Heinritz-Adrian, Oliver Noll, Sascha Wenzel

Publication number: 20120137583Abstract: With a method for supplying an entrained-flow gasification reactor with carbonaceous fuel for the production of a gas that contains CO and H2 and flue ash under pressure and at a temperature above the melting point of the ash, wherein the resulting gas is passed to further treatment stages, particularly at least one synthesis stage, the yield of the liquid products is supposed to be increased in cost-advantageous and simple manner. This is achieved in that the waste gas that is derived from the subsequent treatment stage and still contains hydrocarbons and/or hydrogen is used for pneumatic conveying of the fuel into the entrained-flow gasification reactor.Type: ApplicationFiled: August 10, 2010Publication date: June 7, 2012Applicant: THYSSENKRUPP UHDE GMBHInventors: Max Heinritz-Adrian, Johannes Kowoll, Stefan Hamel

Patent number: 8043577Abstract: With the help of a method and device for nozzle-jetting oxygen into a synthesis reactor, e.g. for oxy-dehydration, with largely axial flow of the gas mixture through a catalyst bed, it is intended to vastly improve the mixing-in and mixing-through of oxygen above the catalyst especially for oxy-dehydration process. This is achieved by feeding the oxygen to a ring distributor system arranged above the catalyst bed in pure form, as air or mixed with inert gas or water vapor and jetting the oxygen onto the catalyst surface through several exit openings in the ring distributor at an inclined angle deviating from the vertical.Type: GrantFiled: December 10, 2004Date of Patent: October 25, 2011Assignee: Uhde GmbHInventors: Johannes Kowoll, Max Heinritz-Adrian, Lothar Semrau

Patent number: 7816576Abstract: The invention relates to a method for producing unsaturated hydrocarbons. According to said method, in a first step, a hydrocarbon, especially a mixture which contains alkanes, essentially no water, and can contain water vapour, is continuously guided through a first catalyst bed provided with standard dehydration conditions. Liquid water, water vapour and a gas containing oxygen are then added to the reaction mixture obtained in the first step and, in a second step, the reaction mixture obtained is then continuously guided through another catalyst bed for oxidising hydrogen and for further dehydrating hydrocarbons. The first catalyst bed can be heated and the heating in the first step is then preferably regulated in such a way that an essentially isothermic operating mode is created.Type: GrantFiled: October 28, 2003Date of Patent: October 19, 2010Assignee: UHDE GmbHInventors: Natarajan Thiagarajan, Max Heinritz-Adrian, Sascha Wenzel, Johannes Menzel
