Effect of Volatile Liquid Phase on Trickle Bed Reactor Performance

Liquid distribution in trickle-beds. An experimental study using computer-assisted tomography

“…In addition, reactions taking place in industrial trickle-bed reactors are often exothermic and can lead to the vaporization of a large fraction of the liquid phase (Collins et al, 1985). In fact, dewetting can occur within a porous catalytic particle for highly exothermic reactions (Harold, 1988).…”

Modeling Catalytic Trickle-Bed and Upflow Packed-Bed Reactors for Wet Air Oxidation of Phenol with Phase Change

“…Among the investigations in the field of reactions in trickle beds with volatile components, Collins et al 4 studied hydrodesulfurization of benzothiophene at a constant pressure of 68 atm and a temperature range of 546-606 K by simulating the global reaction rate in the presence of phase equilibrium effects at each point. The rate was simulated based on four solvents with different volatility to study the influence of relative solvent volatility on the reaction rate.…”

Effects of Vapor-Liquid Equilibria on Coke Deposition in Trickle-Bed Reactors during Heavy Oil Processing. 1. Experimental Results

“…A large and-to us-surprising effect on the coke deposition is related to the extent of evaporation of the feedstock and products. Although the effects of vaporliquid equilibria on the performance of trickle-bed reactors have received significant attention recently (Collins et al, 1985; Kocis and Ho, 1986;Smith and Satterfield, 1986;LaVopa and Satterfield, 1988; Kheshgi et al, 1992), to our knowledge the impact on coke deposition has not been reported as yet.…”
