Characteristics of sewage sludge and solid products obtained from the hydrothermal carbonization (HTC)

This dataset contains experimental data related to the hydrothermal carbonization (HTC) of sewage sludge and the characterization of the resulting solid products (hydrochar) and liquid fractions. The purpose of the dataset is to provide information on how selected HTC process parameters, such as temperature, residence time, and initial pH of the feedstock, influence the distribution of products and their physicochemical properties. The dataset includes measurements of mass distribution, elemental composition (C, H, N, S), and higher heating value (HHV). These data may support research on sewage sludge management, resource recovery, and the potential use of hydrochar as an energy or material resource.
