Abstract:
This work reports our pioneering application of the nuclear magnetic resonance imaging (MRI) technique to the dynamic in situ studies of gas-liquid-solid reactions carried out in a catalytic trickle bed reactor at elevated temperature. The major advance of these studies is that MRI experiments are performed under reactive conditions. We have applied MRI to map the distribution of liquid phase inside the catalyst pellet as well as in the catalyst bed in the operating trickle-bed reactor. In particular, our studies have revealed the existence of the oscillating regimes of the heterogeneous catalytic hydrogenation reaction caused by the oscillations of the catalyst temperature and directly demonstrated the existence of the coupling of mass and heat transport and phase transitions with the chemical reaction. The existence of the partially wetted pellets in the catalyst bed which are potentially responsible for the appearance of hot spots in the reactor was also visualized. The combination of NMR spectroscopy with MRI was used to visualize the spatial distribution of the reactant-to-product conversion within the operating reactor.
