Electrochemical incineration of oxalic acid in the presence of NaCl

2008

Recent researches have demonstrated that electrochemical methods offer an attractive alternative to traditional routes for treating wastewaters containing toxic or/and refractory organic pollutants. The effectiveness of the electrochemical treatment depends on many factors including the presence in solution of specie able to act as mediators. In particular, the effect of chloride ions on the performances of the process has been the object of numerous researches. However, up to now, many practical and theoretical aspects about this argument are not completely clear. In the present work, the anodic incineration of oxalic acid (OA) in the presence of NaCl has been investigated with the aim of …

Effect of Microplastics in Hydrothermal Liquefaction (HTL) of Real Municipal Sludge (RMS)

2022

The work herein was focused to study the effect of the microplastics on the yield and quality of biocrude (BC) produced by hydrothermal liquefaction (HTL) of real municipal sludge (RMS). HTL experiments with RMS containing 3 % w/w microplastics were conducted at 325 °C and 30 min both in the absence and in the presence of CoMo/Al2O3, NiMo/Al2O3 and activated carbon felt (ACF) as heterogeneous catalysts. A white wax was isolated from BC with a yield of 5, 8 and 6 % w/w daf when CoMo/Al2O3, NiMo/Al2O3 and ACF were used respectively. GC-MS analyses demonstrated that oleamide was present in the wax while FT-IR analyses showed the presence of chlorinated organic compounds, affecting negatively t…
