The effect of the inlet liquid distribution on the operation of a trickle-bed reactor is experimentally
investigated, and the observed phenomena are analyzed using a one-dimensional mathematical model with nonequilibrium approaches to describing phase transitions. The modeling shows that, if the fraction of the wetted
surface at the reactor inlet is below unity, then, along a sufficiently long bed, there is always a stationary front
of complete evaporation and complete conversion. The main conclusion within the framework of the considered
one-dimensional model with separate evaporation (on completely wetted granules) and gas-phase hydrogenation
(on dry granules) is that safe operation (the absence of a thermal explosion) can be ensured by complete
suppression of the reaction in the gas phase
