Abstract

The invention concerns a device for synthesis of gas mixtures by mixing a main gas stream with a secondary gas stream. Said device comprises gas supply lines equipped with flow regulators and a mixing chamber wherein emerge the gas feed lines. The mixing chamber includes: a pipe connected to the feed line of the main gas stream so as to form a flow in the pipe and to the feed line of the secondary gas stream such that the secondary gas stream is introduced into the flow of the main gas stream, a static mixer arranged in the extension of the pipe. Said device can be used for testing catalytic compositions.
