A detailed reaction network for the catalytic wet air oxidation (CWAO) of phenol on a CuO/ -Al2O3 catalyst is proposed in this study. The reaction network proposed accounts for all detected intermediate products of phenol oxidation overcoming the usual lumping of compounds. The model is composed by several consecutive and parallel reactions. The parameters of the model were adjusted using exper...

The esterification of ethylene glycol with acetic acid was investigated in a batch reactor in presence of a strongly acidic cation exchange resin, seralite SRC-120, as catalyst in the temperature range of 333 to 363 K. The detailed kinetic study was performed to understand the effect of various process variables such as catalyst loading, ethylene glycol to acetic acid mole ratio, and temperatur...

The application of heterogeneous photocatalysis in industrial scale has been hindered by a lack of simple mathematical models that can be easily applied to reactor design and scale-up. This work intends to use a simple mathematical model for predicting methylene blue (MB) degradation in a slurry-annular photocatalytic reactor using zinc oxide (ZnO) hybridized with reduced graphene oxide (rGO)-Z...

The present work deals with the kinetic analysis and modelling of glycerol (GLY) oxidation in the liquid phase over a supported gold catalyst. A Langmuir-Hinshelwood model was proposed, after considering the effect of the reaction temperature, the NaOH/GLY ratio and the initial concentrations of GLY and GLY-Product mixtures. The proposed model effectively predicted the experimental results, and...

Among the different photocatalysts, TiO 2 ( E g = 3.1 eV, zero charge point (pHpzc 6.3), and surface 55 m /g) is currently most efficient studied semiconductor due to its strong photocatalytic activity, non-toxicity, chemical stability. The elimination of DR-80 on by adsorption in batch mode application heterogeneous photocatalysis onto under UV irradiation. effects contact time (0–60 min), ini...

Synthetic fuels are needed to replace their fossil counterparts for clean transport. Presently, production is still inefficient and costly. To enhance the process of methanol from CO2 H2 reduce its cost, a particle-resolved numerical simulation tool presented. A global surface reaction model based on Langmuir-Hinshelwood-Hougen-Watson kinetics utilized. The approach first validated against stan...

this study is focused on the development of a systematic computational approach which implements genetic algorithm (ga) to find the optimal rigorous kinetic models.a general kinetic model for hydrogenolysis of dibenzothiophene (dbt) based on langmuir-hinshelwood type has been obtained from open literature. this model consists of eight continuous parameters(e.g., arrhenus  and van't hoff paramet...

Photocatalytic degradation of organic components in water by means of TiO2 nanosuspensions under ultraviolet (UV) irradiation represents an efficient method for water purification. In the present paper, a modeling approach is proposed to simulate the involved kinetic processes based on the Langmuir– Hinshelwood mechanism. The extended model also includes the formation of intermediate organic co...
