Hydrochar Enhanced Wood Pellets
… capacity and a pellet composition of 10% hydrochar and 90% loblolly pine. The key deliverables of the design process were also defined by the sponsor. A flowsheet for the process was created that includes process considerations for the minimization of fuel usage as well as minimization of …

Rare Earth Elements (REEs) Recovery and Hydrochar Production from Hyperaccumulators
… was used to convert the leaching residue into hydrochar to achieve a comprehensive utilization of GL biomass. Scanning electron microscopy (SEM) analysis revealed that the original structure of GL was destructed at 180 °C during MHTC, producing numerous microspheres and pores. As the reaction …

Surface-Layer Semivolatiles Impact on Hydrochar Application For Fuel and Environment
… organic compounds from the surface of hydrochar known as secondary char (SC). Over the past decade, studies have shown SC to be a hinderance in HC application for fuels and the environment, due to early burn-out time and phytotoxicity to plants. A major goal of this dissertation was …

REACTIVE TRANSPORT OF IRON AND HYDROCHAR COLLOIDS IN A HYDROCARBON-CONTAMINATED SUBSURFACE ENVIRONMENT
… two potential amendments, a protein-based hydrochar and ferric ammonium citrate, were studied. The hydrochar was studied to determine how effective it is at increasing the bioavailability of P and petroleum hydrocarbons, and ferric ammonium citrate was studied to determine whether it …

Literature Survey of Wet-Waste and Hydrothermal Carbonization System: A Comparative Evaluation
… suitable for the conversion of wet waste to form hydrochar due to it high conversion efficiency, low operating condition and elimination of pre-drying requirement compared to other processes. Hydrothermal carbonization process is performed in a closed heated reactor in which biomass and water …

Hydrothermal carbonization of waste biomass
… into a carbonaceous material, referred as hydrochar. Hydrochar has chemical and physical characteristics that make it similar to fossil peats and lignite. Depending on the process conditions, mostly temperature and residence time, this material can be enriched in its carbon content, …

Hydrothermal Carbonisation of Novel Biomasses
… thermochemically converted into an energy-dense “hydrochar” with strong thermal and elemental similarities to fossil coal. However, key aspects of the HTC reaction remain unknown, especially with regard to the degradation of the key biochemical macromolecules hemicellulose, cellulose, lignin and …

The Comparative Study between the Adsorptive Capacity of Activated Carbon Obtained from the Enhanced Hydrothermal Polymerization Process with Conventional Activated Carbons in the Removal of Micropollutants of Concern
… which is a scarce commodity. In this study, hydrochar derived from primary sludge combined with waste activated sludge was used to produce activated carbon through pyrolysis. The hydrochar derived activated carbon (HC-AC) was characterized along with a commercial granular activated carbon …

Utilization of aqueous product generated by hydrothermal carbonization of waste 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 solid HTC product (hydrochar), however little attention …
