Patent number: 10428035Abstract: In a process for the epoxidation of an olefin by continuously reacting the olefin with hydrogen peroxide in a methanol solvent on a fixed bed epoxidation catalyst comprising a titanium zeolite, the hydrogen peroxide is used as an aqueous hydrogen peroxide solution made by an anthraquinone process, the aqueous hydrogen peroxide solution is mixed with methanol to give a feed mixture and this feed mixture is filtered before being contacted with the fixed bed epoxidation catalyst.Type: GrantFiled: November 1, 2016Date of Patent: October 1, 2019Assignees: Evonik Degussa GmbH, thyssenkrupp Industrial Solutions AGInventors: Matthias Pascaly, Manfred Bärz, Marc Brendel, Robert Jahn, Jürgen Schemel, Michael Dopfer

Patent number: 10428036Abstract: In a process for the epoxidation of propene, comprising the steps of reacting propene with hydrogen peroxide, separating propene oxide and a recovered propene stream from the reaction mixture, separating propane from all or a part of the recovered propene stream in a C3 splitter column, and passing the overhead product stream of the C3 splitter column to the epoxidation step, a propane starting material with a propane fraction of from 0.002 to 0.10 is used, the epoxidation is operated to provide a propane fraction in the reaction mixture of from 0.05 to 0.20 and the C3 splitter column is operated to provide an overhead product stream which comprises a propane fraction of at least 0.04 in order to reduce the size and the energy consumption of the C3 splitter column.Type: GrantFiled: November 25, 2016Date of Patent: October 1, 2019Assignees: Evonik Degussa GmbH, thyssenkrupp Industrial Solutions AGInventors: Willi Hofen, Thomas Haas, Wolfgang Wöll, Bärbel Kolbe, Hans-Christian Dietz, Marc Brendel, Bernd Jaeger, Manfred Bärz, Michael Kleiber

Patent number: 10214504Abstract: Propene is continuously reacted with hydrogen peroxide in a tube bundle reactor comprising a multitude of parallel reaction tubes in the presence of a titanium silicalite catalyst arranged as a fixed bed in the reaction tubes. A cooling jacket encloses the reaction tubes, which has a feed point for cooling medium near the entry of the reaction tubes, a withdrawal point for cooling medium near the end of the reaction tubes and at least one additional withdrawal point upstream of the withdrawal point near the end of the reaction tubes. Cooling medium is fed to the feed point for cooling medium, a part of the cooling medium is withdrawn at the at least one additional withdrawal point and the remainder exits at the withdrawal point near the end of the reaction tubes.Type: GrantFiled: November 1, 2016Date of Patent: February 26, 2019Assignees: Evonik Degussa GmbH, thyssenkrupp Industrial Solutions AGInventors: Marc Brendel, Manfred Bärz, Johannes Kowoll, David Bolz, Willi Hofen, Jürgen Schemel, Bernd Jaeger, Niels Bredemeyer, Bärbel Kolbe, Norbert Ullrich, Michael Dopfer, Wolfgang Wöll, Peter Porscha, Dana Pfenning, Maik Bernhard

Patent number: 9321129Abstract: The invention relates to a machine for material processing with a laser beam, in particular laser welding. It is comprised of a machine guided protective housing with an outlet opening surrounding the laser beam that is pointed at the material during processing. To create a machine for laser beam welding which ensures improved operator and personal safety without completely enclosing the machine, it is suggested that the protective housing contains at least one sensor which measures certain chemical or physical properties. The sensor is connected to the machines control unit which compares the current values with reference values for a measure and, depending on current/reference value comparison, interrupts the laser beam or prevents laser beam activation. In addition a method and arrangement for improved operator and personal safety for operation of such a machine is presented.Type: GrantFiled: September 16, 2013Date of Patent: April 26, 2016Assignee: IPG PHOTONICS CORPORATIONInventors: Andreas Siewert, Manfred Barz, Jörg Thieme, Artjom Fuchs, Ingo Schramm
