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 ...
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 ...
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 ...
Clean oxidation of alcohols in a trickle-bed reactor with liquid flow modulation
(American Chemical Society, 2005-07)
This work reports an experimental investigation of the catalytic oxidation of alcohols, using molecular oxygen as the oxidant and Pt/γ-Al 2O3 (1%w/w) as catalyst, in a trickle-bed reactor with ON-OFF liquid flow modulation ...
