摘要:
The present invention relates to a method and a device for the parallel study of chemical reactions in at least two spatially separated reaction spaces. In particular, the invention is suitable for reactions which are not constant volume reactions and/or for reactions in which fluid flows through at least two spatially separated reaction spaces are intended to be controlled together for all the reaction spaces, or for related subsets of them, in the most straightforward way possible.According to one embodiment, the device according to the invention for the parallel study of chemical reactions comprises at least the following components: (a) at least two spatially separated reaction spaces; (b) on the reaction space input side, at least one common educt feed for the reaction spaces according to (a); (d) on the reaction space output side, at least one connection per reaction space to at least one holding gas feed common to all the reaction spaces, or subsets of them; (e) on the reaction space output side, and downstream of the connection to the holding gas feed according to (d) in the product flow direction, at least one restrictor per reaction space.

The invention relates to a container arrangement for fluids that contain gas, comprising a casing. Said casing is made of a pressure-proof collapsible material, and surrounds at least two chambers. The first chamber is used to receive and release the fluids containing gas via a first connection. The second chamber is a pressure chamber that is provided with a second connection for applying pressure. A flexible wall is arranged between the first chamber and the second chamber. The invention further relates to a method for transporting and releasing liquids containing gas into or from a pressure-proof collapsible casing, in addition to a corresponding pressure-proof, flexible non or slightly elastic covering. A container arrangement for liquids containing gas that has a simple construction, is easy to produce, fill, transport, empty and dispose of or recycle is provided due to the above mentioned invention.

The present invention relates to a process for producing and shaping shaped bodies, in particular heterogeneous catalysts, by means of low-temperature cooling processes, characterized in that a settable and flowable composition, preferably inorganic in nature, for example, a suspension of solids, is introduced as droplets of the desired shape and size into a low-temperature coolant and the frozen droplets are then converted by means of drying and/or calcination processes into the corresponding mechanically stable, solid shaped bodies. The present invention further relates to the shaped body itself which is obtainable by the processes of the invention and the use of the process of the invention for producing and shaping shaped bodies.
