Ethanol oxidation in a trickle-bed reactor using a hydrophobic catalyst. Effect of dilution with hydrophilic particles
(Elsevier Science, 2001-01)
Ethanol oxidation at moderate temperature and atmospheric pressure is carried out in a trickle-bed reactor using a hydrophobic catalyst and pure oxygen as the oxidizing agent. The influence of diluting the hydrophobic ...
Modulation of liquid holdup along a trickle bed reactor with periodic operation
(Pergamon-Elsevier Science Ltd, 2007-11)
Temporal variations of the liquid holdup in a mini-pilot scale trickle bed reactor cold-mockup, induced by an ON-OFF liquid flow modulation strategy of operation, are explored at different axial positions. The reactor is ...
Enhancing performance of a trickle bed reactor at low liquid flowrates
(Planta Piloto de Ingeniería Química, 2002-03)
The impact of liquid volatility, gas solubility, mass transfer and kinetics-diffusion on the reactor performance at incomplete wetting was observed. Three different reactor zones of prepacking inert section, catalytic bed ...
Dryout phenomenon in the periodic operation of a trickle bed reactor
(Planta Piloto de Ingeniería Química, 2004-11)
Periodic operation was investigated for the hydrogenation of aplpha-methylsyrene to cumene over 0.5% Pd on alumina spheres. The effect of several variables such as gas flow rate, gas and liquid composition, and liquid feed ...
Phenomenological approach to interpret the effect of liquid flow modulation in trickle bed reactors at the particle scale
(Pergamon-Elsevier Science Ltd, 2005-11)
This work analyzes the influence of liquid flow modulation on the behavior of a reaction occurring in a spherical porous particle within a trickle bed reactor. A single first-order reaction between a gaseous reactant and ...
Prediction of thermal behavior of trickle bed reactors: The effect of the pellet shape and size
(Elsevier, 2017-08)
Heat transfer plays an important role in several applications of packed bed reactors with cocurrent downflow of liquid and gas (widely known as trickle-bed reactor – TBR). A literature survey shows that the amount of ...
