Special Issue Information

Dear Colleagues,

Catalytic wet peroxide oxidation (CWPO) has been experiencing a great deal of increasing interest from specialists in water treatment. This interest arises from the simple operation and cost of the process, capable of being applied at room temperature and atmospheric pressure, providing a suitable catalyst is used. In the quest to bring CWPO to the forefront position of advanced treatment technologies, researchers are covering different topics, including catalyst development, characterization, mechanistic and kinetic assessment, catalyst stability and deactivation, in-situ production of hydrogen peroxide, process intensification and optimization. In addition, topics related to new reactor and process design and configurations and application in the treatment of complex multi-phasic systems, as well as process scale-up and integration in water treatment units, are also subject of focus.

Authors with expertise in any topic related to catalytic oxidation with hydrogen peroxide are cordially invited to submit their manuscripts to this Special Issue of Catalysts. Significant full papers and review articles are very welcome. The Special Issue will cover various aspects related to CWPO in all of its diversity, as well as other areas on the boundaries.

The current work proposes a strategy for the valorization of compost obtained from municipal solid waste, through its activation with H2SO4 and thermal treatment at 400–800 °C to produce low-cost catalysts for wet peroxide oxidation. All the developed materials were catalytically active for the aqueous solution oxidation of 2-nitrophenol (C2-NP,0 = 0.5 g L−1) and 4-nitrophenol (C4-NP,0 = 5.0 g L−1). In particular, using the catalysts prepared by thermal activation of the compost (with and without subsequent treatment with H2SO4), complete removal of both model pollutants was achieved after 24 h (at 50 °C, initial pH 3, Ccat = 2.5 g L−1, and employing a stoichiometric quantity of H2O2 needed for the total mineralization of the pollutants). In a cyclohexane–water mixture (simulating biphasic oily wastewater), 4-nitrophenol is also completely removed by the catalyst not treated with H2SO4. In contrast, the removal of 2-nitrophenol decreased to 93% due to its higher lipophilic character. Thus, this work demonstrates that active catalysts for wet peroxide oxidation can be obtained by using as a precursor a matured compost derived from municipal solid waste. Full article

This work aims to present an industrial perspective on Catalytic Wet Peroxide Oxidation (CWPO) technology. Herein, process simulation and experimental design have been coupled to study the optimal process conditions to ensure high-performance oxidation, minimum H2O2 consumption and maximum energetic efficiency in an industrial scale CWPO unit. The CWPO of phenol in the presence of carbon black catalysts was studied as a model process in the Aspen Plus® v11 simulator. The kinetic model implemented, based on 30 kinetic equations with 11 organic compounds and H2O2 involvement, was valid to describe the complex reaction network and to reproduce the experimental results. The computer experiments were designed on a six-factor Doehlert Matrix in order to describe the influence of the operating conditions (i.e., the different process temperatures, inlet chemical oxygen demands, doses of H2O2 and space time) on each selected output response (conversion, efficiency of H2O2 consumption and energetic efficiency) by a quadratic model. The optimization of the WPO performance by a multi-criteria function highlighted the inlet chemical oxygen demand as the most influential operating condition. It needed to have values between 9.5 and 24 g L−1 for autothermal operation to be sustained under mild operating conditions (reaction temperature: 93–130 °C and pressure: 1–4 atm) and with a stoichiometric dose of H2O2.
