Hydrothermal carbonization (HTC) emerges as a promising technology to reduce the
volume of activated sewage sludge (SS) and generate solid products as fuels. During HTC …

Hydrothermal liquefaction (HTL) of biomass, especially that of high moisture such as
microalgae, macroalgae, sludge, manure, and food waste, for the production of bio-oil has …

The significant growth of the global population, as well as the increase in energy demand
and the limitations of energy generation from fossil fuels, have become a serious challenge …

Biomass is a type of renewable and sustainable resource that can be used to produce
various fuels, chemicals, and materials. Nitrogen (N) in biomass such as microalgae should …

In this study, the aqueous phase produced from the hydrothermal carbonization (HTC) of
sewage sludge (SS) with pure water was reused for the HTC of fresh SS, aiming to maximize …

Co-hydrothermal carbonization (Co-HTC) coupled with aqueous phase (AP) recirculation
has huge potential to improve hydrochar production. In this study, three model compounds …

The imbalance between the energy demand and supply and environmental pollution makes
it necessary to develop renewable energy as an alternative energy source. Hydrothermal …

Biomass is the most abundant and low-cost renewable source for the production of value-
added nitrogen-containing compounds. However, a large amount of water exists in natural …

This contribution discloses a new methodology for the preparation of N-doped carbon via
the hydrothermal carbonization (HTC) of sewage sludge (SS). The aqueous phase served …

Biomass resources have infinite possibilities for introducing nitrogen, sulfur, or phosphorus
heteroatoms into their structures by virtue of controllable carbon–heteroatom bond …
