摘要： A process for forming and for catalytically converting an ignitable gas mixture is proposed, in which at least a first gas or gas mixture comprising oxygen and a second gas or gas mixture comprising one or more oxidizable compounds are mixed to give the ignitable gas mixture, where the ignitable gas mixture is supplied to a reaction zone (12) of a reactor (1). The first gas or gas mixture and the second gas or gas mixture are fed into a mixing chamber (11) having a boundary wall (13) provided with a number of passages (131), where the first gas or gas mixture is fed into the mixing chamber (11) through the passages (131) in the boundary wall (13) and where the second gas or gas mixture is fed into the mixing chamber (11) by means of one or more feed conduits (14) which have feed orifices (141) and extend into the mixing chamber (11). The present invention likewise provides a corresponding reactor (1).

摘要： A process for producing one or more olefins is proposed in which a reaction input containing one or more paraffins is formed and in which a portion of the paraffin(s) present in the reaction input is converted by oxidative dehydrogenation into the olefin(s) to obtain a process gas, wherein the process gas contains at least the olefin(s), the unconverted paraffin(s), oxygen and carbon monoxide and wherein at least a portion of the process gas is subjected to a low temperature separation in which at an operating pressure level one or more gas fractions enriched in oxygen and carbon monoxide compared to the process gas are formed. It is provided that in the low temperature separation in the formation and/or for the conduction of the or at least one of the gas fractions one or more containers and/or one or more conduits having a burst pressure of at least ten times the operating pressure level are used and that the container or at least one of the containers via the or at least one of the conduits is connected to one or more heat exchangers, wherein a total length of the or of the at least one conduit between the or the at least one container and the heat exchanger(s) is not more than fifty times the internal diameter of said conduit. A corresponding plant (100) likewise forms part of the subject matter of the invention.
