Performance enhancement of trickle bed reactor for the removal of organic compounds from petroleum industrial wastewater

[摘要] Catalyst Wet Air Oxidation of phenol Promoted with Hydrogen Peroxide (PP-CWAO) was studied experimentally in this work using a trickle bed reactor operating in both steady state and periodic operation (liquid flow modulation). The effect of cyclic parameters (cycle period and split) are investigated under the same conditions chosen on the basis of the steady state results for PP-CWAO. The results showed that the PP-CWAO of phenol are kinetically controlled for steady state operation. For periodic operation, the time average conversion enhancement is indeed quite considerable in liquid flow modulation as split is lowered from steady state cycle split (σ = 1) to a value of (σ = 0.5) and reached as much as 6.66 % over the steady state at cycle period (τ p ) = 15 sec.
