HYDROTHERMAL CARBONIZATION OF MUNICIPAL SOLID WASTE: COMPARISON TO CURRENT WASTE MANAGEMENT TECHNIQUES AND ASSOCIATED ENVIRONMENTAL IMPLICATIONS

摘要

Hydrothermal carbonization (HTC) is a wet, relatively low temperature (180 - 350 °C) thermal conversion process that, under autogenous pressures, has been reported as a means to convert carbohydrates into a carbonaceous residue often referred to as hydrochar. This process has been shown to be exothermic in nature for pure compounds and energetically more advantageous than dry carbonization processes (i.e., pyrolysis) for feedstocks containing moisture. Recently, this technique has been revived and explored as a means to create novel low-cost carbon-based nanomaterials/nanostructures from carbohydrates. Recently, this technique has been explored as a sustainable waste management technique.
