System of 8 parallel plug-flow reactors for fast kinetic data acquisition. The 8 reactors are embedded in 4 furnaces, with individual control of pressure and temperature in each block. Possibility to feed 3 gas components per reactor from 3 different MFC: CH₄ , N₂ and optional H₂ . One liquid pump is installed per reactor for an optional liquid flow. Pressures ranging from 0 to 100 bar, temperatures up to 500°C, amount of catalyst required on the order of grams. Two GC chromatographs available with FID detector for online analysis of the gasses and offline analysis of liquid by an autosampler
