摘要： This invention relates to an arrangement, equipment and method for testing heterogeneous catalysts for short contact time reactions. It is a novel application of capillary technique where capillary tubing and separation columns are used as on-line sampling probes as well as for separation of compounds. The equipment comprises a furnace which gives a broad and uniform temperature profile, a tube reactor, adapter units, gas and liquid injection valves, a gas chromatograph furnished with suitable detectors, mass-flow and temperature measurement controllers, an injector, a reactor and column head pressure adjusting valve, an on-line sampling application with capillary technique, with splitting of sample with capillary technique, simultaneous detection of pulse mode, hydrogen and compound responses.
