  • Publication number: 20230086177
    Abstract: The present invention relates to a method for preparing polyether carbonate polyols by adding alkylene oxide and carbon dioxide to a H-functional starter substance in the presence of a DMC catalyst or a metal complex catalyst based on the metals cobalt and/or zinc, wherein (?) alkylene oxide and carbon dioxide are added to a H-functional starter substance in a reactor in the presence of a DMC catalyst or a metal complex catalyst based on the metals cobalt and/or zinc, characterized in that the alkylene oxide contains a proportion of 5 to 50 wt. % ethylene oxide, based on the overall weight of the alkylene oxide used, and the addition of the ethylene oxide is carried out in an atmosphere containing carbon dioxide.

  • Patent number: 10253655
    Abstract: A method for coupling a gas turbine connected to a generator and a steam turbine, wherein the generator has an excitation winding, the excitation of which can be changed by changing an excitation current flowing through the excitation winding, the method having the following steps: a) accelerating and/or decelerating the steam turbine in such a way that the coupling takes place with a target coupling angle; b) if necessary, changing the excitation current such that the excitation of the excitation winding changed in this way leads to a changed polar wheel angle, wherein the polar wheel angle is changed in such a way that the achieving of the target coupling angle is supported. In an analogous method, the polar wheel angle is changed for the purposes of improved decoupling. A corresponding control device is for coupling a gas turbine connected to a generator.
