Abstract: The invention relates to a process and an apparatus for catalytically reforming hydrocarbons or alcohols to hydrogen in a plurality of partial reactions. The plurality of partial reactions are performed individually and/or in combinations of at least two of the plural partial reactions in a microreactor network comprising microreactors and channels formed between the microreactors, starting substances and/or reaction products of the plural partial reactions being conveyed through at least part of the channels between reactor spaces of the microreactors. Reaction progress of the plural partial reactions in the microreactor network is controlled by way of process control means for controlling process parameters.

Abstract: In a small animal surgery suite, a ventilation system (20) is provided to reduce the amount of anaesthetic released. The ventilation system has at least one inlet (40, 88) which is connected to an exhaust and positioned close to where anaesthetic is released. Where the anaesthetic is released from an induction station (12), where animals are initially anaesthetized, the inlet can be provided above the station. Where the anaesthetic is released from a breathing station (14), where the animals are operated on, the inlet can be provided next to the part of the breathing station (80) into which the animal's nose is inserted.
