Wet oxidation of thermochemical aqueous effluent utilizing char catalysts in microreactors

Production of bio-oil or biocrude from thermochemical processes such as pyrolysis and hydrothermal liquefaction (HTL) respectively, is considered a promising path for the production alternative fuels chemicals. However, these technologies create an aqueous phase byproduct contaminated with high concentrations organic compounds. Traditional wastewater rely on biological processing which not resistant to toxic levels compounds present. Wet oxidation byproducts dilute stream potential pathway value-added products acetic acid. was carried out at near ambient temperature (75–90 °C) atmospheric pressure in presence hydrogen peroxide oxidant char catalyst activator three individual phases. The phases were thoroughly analyzed by total carbon (TOC), chemical oxygen demand (COD), Total Phenol, Acid Number, constituents via gas chromatography mass spectroscopy (GCMS). HTL quite similar every regard can be seen their COD 44.8 41.5 g O2/L respectively. much more complex nature 10X higher 364.5 O2/L. This validated ICRMS analysis revealed molecules visible regular spectrometry. All tests conducted cellulose-based doped Nitrogen Iron Oxide. experiments microscale-based continuous reactor due its superior performance reduction transport limitations. Oxidation small molecular weight acid achieved final containing between 0.555 5.04 mg acid/g liquid effluents. Our results confirm that wet process effluents biomass conversion processes.
