Hydrothermal carbonization is a wet thermal conversion technique that is gaining significant attention as a sustainable and environmentally beneficial technique for biomass and waste transformation to value-added products. Carbonization investigations have been performed on a variety of feedstocks, ranging from pure substances, such as glucose and cellulose, to more complex feedstocks, such as mixed municipal solid waste, food waste, and animal wastes. Results from these studies have demonstrated that carbonization products are greatly influenced by both feedstock properties and process conditions. A survey of existing HTC-related literature was conducted. Studies reporting on hydrothermal treatment processes occurring between 180 and 350 oC were collected. Process related information (e.g., reaction time, reaction temperature, reactor volume), feedstock properties (e.g., ultimate and proximate analysis), and experimentally collected carbonization product data from each study were tabulated.  Process information and feedstock properties are used as parameters to develop a family of numerical models.  Bayes inference is used to calculate the probability of each model given the family of models.  The models with the highest probabilities are presented and discussed.
