Catalytic studies in wet oxidation of effluents from formaldehyde industry
Silva, Adrián M. T.; Castelo-Branco, Isabel M.; Quinta-Ferreira, Rosa M.; Levec, JanezDevelopment and design of active catalysts for the oxidation of formaldehyde present in wastewaters is of great importance. In this context, catalytic performance studies for oxidation of high formaldehyde containing solutions (1500 ppm) were carried out in a semibatch high-pressure reactor at 190-220°C and 15-35 bar of oxygen partial pressure. The removal efficiency of total organic carbon (TOC) was evaluated ...
Catalytic and Noncatalytic Wet Oxidation of Formaldehyde. A Novel Kinetic Model
Silva, Adrián M. T.; Quinta-Ferreira, Rosa M.; Levec, JanezFormaldehyde is a carcinogen compound and one of the most important pollutants contained in wastewaters. Three different treatments were evaluated in a high-pressure batch reactor for the total organic carbon (TOC) degradation of formaldehyde solutions: thermolysis, noncatalytic wet oxidation, and catalytic wet oxidation over a CuO−ZnO/Al2O3 catalyst. The absence of the catalyst leads to a predominant inductio...
