Hydrothermal carbonization of waste biomass
… content higher than 60%). As a matter of fact, biomass is transformed into hydrochar because of the properties of hot pressurized water, that acts both as a reactant and as a catalyst. The HTC process has been studied from many years, although at present not all the chemical reactions that occur …

Hydrothermal liquefaction for energy recovery from high-moisture waste biomass
… technology for converting high-moisture waste biomass into energy dense “biocrude” oil that can be used for direct combustion or refined for transportation grade fuels. This study investigates the influence of biomass composition on the chemical characteristics of hydrothermal …

Utilization of aqueous product generated by hydrothermal carbonization of waste biomass
… 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) created via HTC. A majority of the research to date has focused on the …

PROTEIN HYDROLYSATES FROM AGRICULTURAL WASTE BIOMASS: ENZYMATIC PREPARATION, BIOLOGICAL ACTIVITIES AND TECHNO-FUNCTIONAL PROPERTIES
… – crude oil, coal and natural gas – by renewable biomass as a sustainable feedstock for the manufacture of chemicals and fuels. However, research on biomass valorization has mainly focused on the conversion of the C-, H-, and O-containing fractions (i.e., carbohydrates, lignin and triglycerides), …

Surface-Layer Semivolatiles Impact on Hydrochar Application For Fuel and Environment
Recovering waste biomass from agricultural and industrial processes is a means of upscaling a carbon source that otherwise would contribute to greenhouse gas emissions. Thermochemical conversion processes transform agro-industrial waste biomass into liquid bio-oils and solid chars, which have …

Acoustical characteristics of oil palm mesocarp fibres
Natural fibres are availability biomass, plentiful in agricultural waste and eco�friendly materials. Currently, it is become the major reasons for emerging renewable materials in sustainable technology. Therefore, this study discusses the acoustical characteristics of agro-waste biomass fibres from …
