This review article focuses on recent studies using hydrothermal carbonization (HTC) for producing hydrochar and its potential application as a solid fuel pellet. Due to the depletion of fossil fuels increasing greenhouse gas (GHG) emissions, need carbon-neutral sources has increased. Another environmental concern relates massive amount industrial processing municipal waste, which are often und...

Carbon quantum dots (CQDs) are nanomaterials with a particle size range of 2 to 10 nm. CQDs have wide applications such as medical diagnostics, bio-imaging, biosensors, coatings, solar cells, and photocatalysis. Although the effect various experimental parameters, synthesis method, reaction time, etc., been investigated, different feedstocks on has not studied yet. In this study, were synthesiz...

Hydrothermal carbonization (HTC) is considered as an efficient and constantly expanding eco-friendly methodology for thermochemical processing of high moisture waste biomass into solid biofuels valuable carbonaceous materials. However, during HTC, a considerable amount organics, initially present in the feedstock, are found process water (PW). PW recirculation attracting increasing interest hyd...

Shrimp shell is a popularly consumed seafood around the globe which generates substantial quantity of solid wet waste. Hydrothermal carbonization (HTC) could be viable pathway to convert shrimp waste into energy-dense hydrochar. The present study aims assess fuel properties, physicochemical attributes, and combustion properties hydrochar generated with wide range HTC temperatures (110–290 °C). ...

Effects of the type of biomass and temperature, with longer residence time, on physicochemical characteristics of hydrochar were investigated. Different carbonization conditions were applied with the goal of producing hydrochars having better physicochemical properties. After the carbonization process, the pyrolysis and combustion behaviors of hydrochar were evaluated. The effect of temperature...
