摘要:
The present invention relates to an integrated plant which comprises a plant for the electrothermic production of ethyne and a plant for electricity generation, the plant for the electrothermic production of ethyne being connected to the plant for electricity generation via a conduit and electricity being generated in the plant for electricity generation from a product gas obtained in the plant for the electrothermic production of ethyne. This integrated plant affords flexible use of electricity by a method in which, at times of a high electricity supply, the plant for the electrothermic production of ethyne is operated and at least some of the hydrogen and/or gaseous hydrocarbons obtained in addition to ethyne is stored and, at times of a low electricity supply, stored hydrogen and/or gaseous hydrocarbons are fed to the plant for electricity generation.
摘要:
A method for providing control power for an electricity network in which at least one energy store connected to the electricity network supplies energy to the electricity network as required and/or takes up energy from the electricity network as required, the control power being delivered in dependence on a frequency deviation from a setpoint value of a network frequency, a tolerance with respect to the frequency deviation being used to set a charging state of the energy store at a same time as providing the control power by the energy store. A device for carrying out such a method includes a control system and an energy store, the device being connected or connectable to an electricity network, the control system being connected to the energy store and controlling the control power that is given off and/or taken up by the energy store.

Reactions between at least two fluid reactants are performed in a reactor comprising wall elements (1), slot-shaped reaction spaces (3) and cavities (5) for conducting a fluid heat-carrier through. Depending on the process and throughput, a modular structural design is chosen wherein an arbitrary number of wall elements (1) are assembled to a right-parallelepipedal block (24), the reaction spaces (3) are formed between lateral surfaces (2) of right-parallelepipedal wall elements (1), the reactants are introduced into the reaction spaces (3) from edge regions of one side of the block (24) and are conducted through the reaction spaces (3) in parallel flows and the fluid heat-carrier is conducted through the tubular cavities (5) extending in the interior of the wall elements (1).
摘要:
Granulates which contain titanium silicalite-1 are composed of silicon dioxide, titanium dioxide and titanium silicalite-1 crystals. The granulates can be prepared by spray-drying or spray granulating the crystallization suspension. The granulates may be used as suspension catalysts, such as for the epoxidation of olefins using hydrogen peroxide.

摘要:
A method providing control power for an electricity network in which at least one energy store supplies energy to the electricity network and/or takes up energy from the electricity network dependent on a frequency deviation from a desired frequency of the electricity network, a deadband being prescribed around the desired frequency. The frequency deviation from the network frequency is measured with greater accuracy than a width of the deadband and a bandwidth within the deadband is chosen dependent on a charging state of the energy store, with control power being provided outside the bandwidth. A device carrying out the method includes at least one energy store and a control system controlling control power of the energy store in an open-loop or closed-loop manner, the energy store being connected to an electricity network such that energy can be fed into the electricity network and can be removed from the electricity network.
