Comparative studies on water- and vapor-based hydrothermal carbonization: process analysis

Hydrothermal carbonization (HTC) reactor systems used to convert wet organic wastes into value-added hydrochar are generally classified in the literature as liquid water-based (HTC) or vapor-based (VTC). However, the distinction between the two is often ambiguous. In this paper, we theoretically developed models for predicting reactor pressure, volume fraction of liquid water, and water distribution between phases as a function of temperature., Methods are described in the manuscript http://dx.doi.org/10.3390/en13215733. Descriptions corresponding to each figure and table in the manuscript are placed on separate tabs to clarify abbreviations and summarize the data headings and units.
Figures 1 and 6 were generated using the NIST Reference Thermodynamic and Transport Properties software (REFPROP) v. 10.0 (https://www.nist.gov/srd/refprop).  For Fig.6, the temperatures and moalr volumes of different feedstock and HTC conditions reported in the literature were plotted to the T-v diagram generated from the REFPROP.  These literature data points are included in the xlsx file.,
