In this paper, the specified issues that occurs in the numerical modeling of complex phenomena of chemical reactions intensified with forced fluid flow in the thermocatalytic reactor channels on the intermetallic phase of Ni3Al are presented. Based on the example of flowing mixture containing helium contaminated by methanol in a horizontal microchannels, heated from the outside, received results of the experiment were shown and compared with computational fluid dynamize calculations. However, standard version of commercial code have been expanded by user definedfunctions. These extensionstransformed the calculation mechanisms and algorithms of computational fluid dynamize codes adapting them for the micro-flow cases and increased chemical reactions rate on an interphase between fluid and solid. Results obtained on the way of numerical calculations were compared with experimental data receiving satisfactory compliance.
Opisano zasadę działania urządzenia do pobierania próbek reagentów w badaniach kinetyki reakcji katalitycznych metodą mikroreaktorową z przyłączonym chromatografem gazowym. Zastosowanie sterowania komputerowego pozwala zautomatyzować cykl pomiarowy w chromatografie gazowym oraz pobierać próbki reagentów niezależnie od czasu ich analizy.

The base of working of attachment for reagents sampling in the investigation of kinetics of catalytic reactions by microreactor method with coupled gas chromatograph have been discussed. The use of computer controlling makes possible to automatize the measurement cycle and to sample reagents irrespective of time of their analyzing in gas chromatograph.
