Abstract:
Process for the production of synthesis gas (3), in which methane and carbon dioxide (2) are introduced into a reaction space (R) and reacted in the presence of a solid (W) at elevated temperatures to give hydrogen and carbon monoxide. Methane and carbon dioxide are passed through a carbon-containing granular material (W) and reacted in a high-temperature zone (H).
Abstract:
The invention relates to a centrifugal droplet separator for separating liquid droplets from a feed gas flow containing said droplets, having a vertical longitudinal axis and a circular cross-section, having a shell (1) and hoods (2) on the upper and lower ends of the shell (1), having a tangential supply (3) of the feed gas flow containing the liquid droplets on the shell (1) and having 10 outlet socket (4) for the liquid separated in the centrifugal droplet separator in the region of the lower hood (2) and having a gas outlet socket (7) for the gas flow purified in the centrifugal droplet separator in the region of the lower hood (2), which is characterized in that there are two, three or more inlet openings (9) arranged symmetrically on the circumference of the upper hood (2) for a tangential 15 supply of flushing fluid in the same direction as the supply of the feed gas flow containing the liquid droplets.
Abstract:
The invention relates to a liquid-impregnated foamed plastic part consisting of a) between 1 and 10 % by volume of an aminoplastic-based, open-pored foamed plastic and b) between 90 and 99 % by volume of a component that is liquid at 25°C, such as aromatic or aliphatic hydrocarbons, alcohols, ketones, water or aqueous dispersions, and to the uses of said part for transporting or metering liquids, for freeze-explosion purposes, for projectile energy absorption or as a latent heat accumulator.
Abstract:
The invention relates to a method for producing polyisobutenes, in which isobutene is polymerized in liquid organic phase in the presence of a Lewis acid catalyst, the organic phase is mixed with an aqueous terminating agent in a dynamic mixer in order to terminate the reaction, said dynamic mixer comprising an axially symmetrical mixing chamber formed by a peripheral wall and two end walls as well as a mixing rotor that is rotatably driven therein. The organic phase is introduced via a first inlet located in the peripheral wall while the aqueous terminating agent is introduced via a second inlet located in the peripheral wall, and a finely dispersed mixture of the organic phase and the terminating agent is withdrawn via an outlet located in the peripheral wall and is delivered to a phase separation process. The inventive method is used for producing highly reactive polyisobutenes and/or polyisobutenes having a narrow molecular weight distribution.
Abstract:
The invention relates to a method for producing a polyalkenyl amine in which the solvent used for the production is exchanged for a different solvent.
Abstract:
The invention relates to a method for performing endothermic process, characterized in that the annual average total energy required for the endothermic process originates from at least two different energy sources. One of the energy sources is an electrical energy source, the power of which varies between 0 and 100% of the required total power, and three different energy modes individually can provide the total required power for the endothermic process: (i) exclusively electrical energy, (ii) a mixture of electrical energy and at least one additional non-energy source, or (iii) exclusively non-electrical energy. The transition time in which the change from one energy mode to another energy mode is completed 30 minutes at most.
