Unsteady-state operation of trickle-bed reactor for dicyclopentadiene hydrogenation

Yield Optimization in a Cycled Trickle‐Bed Reactor: Ethanol Catalytic Oxidation as a Case Study

“…These reactors are widely used in chemical, petrochemical, and petroleum industries, in biochemical and electrochemical processing, and in waste water treatments [1]. The effect of cycling on selectivity of complex reactions is a question that has been scarcely addressed although experimental studies have shown that ON-OFF LFM affect the product distribution of consecutive reactions [3][4][5][6][7][8]. Liquid flow modulation (LFM) results in significant increase in production capacity and conversion compared to steady-state operation for gaslimiting reactions [2].…”

“…More recently, Liu et al [7] studied the effect of unsteadystate operation on a TBR in which the exothermic hydrogenation of dicyclopentadiene (DCPD) over a Pd/Al 2 O 3 catalyst takes place. For cycle periods from 60 to 400 s and splits from 0.25 to 0.75, the final product yield is enhanced compared to the one attained under steady-state operation.…”

Optimal Design of a Multifunctional Reactor for Catalytic Oxidation of Glucose with Fast Catalyst Deactivation

“…Modulation of mostly composition and/or feed flow rate was researched by e.g. : Boelhouwer, et al (2002), Silveston & Hanika (2002), Tukač, et al (2003), Silveston & Hanika (2004), Liu, et al (2008 etc., with the aim to improve chemical reactors performance through forcing the reactor to operate under transient rather than steady-state conditions. Silveston (1998) in his monograph pays attention to several catalytic processes operated in this way.…”

Dynamic evaluation for liquid tracer in a trickle bed reactor

“…The largest applications of TBRs occur in industrial processes, including hydrotreating, hydrodesulfurization, petroleum refining, petrochemical, hydrogenation, oxidation, hydrodenitrogenation, biochemical, and detoxification of waste water industries (AlDahhan et al, 1997;Dudukovic et al, 1999;Liu et al, 2008;Ayude et. al., 2008;Augier et al, 2010;Rodrigo et al, 2009).…”
