Summary

In order to obtain an atmosphere with low ethylene concentration, catalytic oxidation of ethylene was used. The efficiency of the catalytic unit is 90 to 95% depending on the flow of ambient atmosphere through the unit. The catalytic temperature is 320 °C. The mathematical model of ethylene dynamics is based on differential equations of first order and coincides well with experimental data. The mathematical equations allow the prognosis of the development of ethylene concentration in the case of continual oxidation of ethylene. For apples and the chosen experimental chamber the limit concentration of ethylene was 20 µl. This catalytic system seems to be useful especially for horticultural products with low production of ethylene of up to 5 µl/kg.h.
