The influence of the catalyst on the CO formation during catalytic wet peroxide oxidation process

Herein, the formation of carbon monoxide as a harmful product upon Catalytic Wet Peroxide Oxidation process is studied in presence different solid catalysts: an iron supported activated catalyst, metal-free catalyst based on Graphene Nanoplatelets, and 1.6 wt.% Fe containing Cr2AlC MAX phase catalyst. The CWPO performance evolution gas effluent have been compared to that obtained conventional Fenton process. Carbon yield released was significantly lower relation process, where CO concentration reaches maximum 6651 mg/Nm3. By contrast, carbon-Fe and, notably, Nanoplatelets catalysts, more progressive phenol aromatics intermediates oxidation resulted much at exit reactor 2454 mg/Nm3, 170 mg/Nm3 187 respectively. Hence, when homogeneous oxidation, results be sustainable treatment for high-loaded phenolic wastewaters by decreasing hazardous gaseous emissions avoiding this way secondary pollution during
