Upgrading biomass by hydrothermal and chemical conditioning
… than one hour. In hydrothermal carbonization (HTC), also known as wet torrefaction, biomass is treated with hot compressed subcritical water (200-260oC) for 5 min-8 h. The solid product, HTC biochar, contains about 55-90% of the mass and 80-95% of the fuel value of the original feedstock. The …

Sustainable biomass-derived hydrothermal carbons for energy applications
… In this regard, hydrothermal carbonisation (HTC) has shown to be an effective means of conversion of biomass-derived precursors into functional carbon materials. However the attempts to convert raw biomass, in particular lignocellulosic one, directly into such products have certainly been …

Improvement in the cooking and physico-chemical characteristics of hard-to-cook cowpeas by pre-conditioning and micronization
… of cowpeas is impaired by the hard-to-cook (HTC) defect, which develops when cowpeas are stored at high temperature and humidity conditions. HTC cowpeas require extended time to cook and have decreased protein, starch, vitamin availability and poor textural quality. The extended cooking time …

Utilization of aqueous product generated by hydrothermal carbonization of waste biomass
Hydrothermal carbonization (HTC) is a thermochemical treatment process that allows for the conversion of relatively dilute biomass slurries into value added products which are hydrochar and filtrate. This investigation focuses on the potential for utilization of the filtrate (aqueous by-product) …
