This contribution focuses on the induced oscillatory behaviour observed during the continuous hydrogenation of 2MP in a packed bed microreactor. Induced reproducible oscillations have been studied using the on-line gas chromatograph (GC-FID/TCD) and a catalyst bed temperature monitoring. Effects of the temperature, thermal conductivity and space velocity on the properties of induced oscillations have been investigated in detail. The study results revealed extremely high sensitivity of the oscillatory behaviour to the heat transfer conditions in the system. Experimental tests focusing on the space velocity effect revealed a significant influence on the oscillation amplitude height and period phase length with the high reaction rate. Based on the character of the induced oscillations, they have been classified as thermo-kinetic oscillations1 as they are resulting from the interaction between the exothermic reaction, heat transfer and a reversible decrease in the catalyst activity.
