INDUCED OSCILLATORY BEHAVIOUR DURING 2-METHYLPROPENE (ISOBUTENE) HYDROGENATION IN A PACKED BED MICROREACTOR

Popis výsledku v původním jazyce

For better understanding of the industrial C4 fraction hydrogenation process, a reaction study has been performed in a laboratory environment. Hydrogenation of 2 methylpropene (isobutene, 2-MP) over commercial catalyst has been investigated experimentally as a model reaction. This continuous hydrogenation in gas phase has been carried out on the platinum catalyst Cherox 3902 under the temperatures up to 110°C and hydrogen pressure 20 barg. This contribution focuses on the induced oscillatory behaviour observed during the continuous hydrogenation of 2 MP 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.
