Název v původním jazyce

Design, Scale up and Safe Piloting of Thymol Hydrogenation and Menthol Racemisation

Popis výsledku v původním jazyce

A bench scale trickle-bed reactor was designed, constructed and extensively used in the optimisation of the hydrogenation of thymol to racemic menthol. The process was successfully operated for more than 660h in a bench scale reactor and subsequently scaled up to a pilot scale trickle-bed reactor. The pilot scale experiments were used to verify process scale-up and generate material for menthol resolution and downstream processing. Both the bench and pilot scalereactors were operated as adiabatic systems and the operation was found to be safe and reliable. Safety problems leading to formation of undesirable hot spots were experienced as consequence of insufficient catalyst wetting, high thymol concentration in the feed (above 40 wt.%) and because of possible equipment, operation and power failure.
