20080241021 | Distribution Device for a Gas-Liquid Phase Mixture for Apparatus - Distributor device ( | 10-02-2008 |
20090220391 | Distribution Device for a Gas-Liquid Phase Mixutre for Apparatus - A shell-and-tube reactor is disclosed. Contact tubes are disposed within a cylindrical housing and are secured to tube plates. Gas and liquid phases are received via a feed opening in a lower end cap and discharged via an upper end cap in the housing. A distributor device for a gas phase/liquid phase mixture is disposed below the lowermost tube plate. The distributor device includes a distributor plate and a predistributor. The distributor plate is arranged horizontally within the housing and includes an active area having through-openings and a downward-extending margin, but does not extend over the entire cross section of the housing. The predistributor includes a second distributor plate disposed between the feed opening and the first distributor plate, wherein the second distributor plate includes a second active area with second through-openings and a second downward-extending margin. | 09-03-2009 |
20100222209 | USE OF SHAPED BODIES HAVING CATALYTIC PROPERTIES AS REACTOR INTERNALS - The invention relates to moulded bodies having catalytic properties, obtained due to a method that comprises the following said steps: a) a moulded body is produced by means of a powder-based rapid-prototyping-method, b) said moulded body is optionally heat-treated, c) at least one catalytically active component is optionally applied to the moulded body, d) said moulded body is optionally subjected to another heat-treatment. The steps b, c) and/or d) can be performed several times. Said moulded bodies are used as reactor fittings in heterogeneously catalyzed chemical reactions. | 09-02-2010 |
