Catalytic hydrothermal gasification of hydrothermal liquefaction wastewaters: influence of catalysts

, 2019
Hydrothermal liquefaction (HTL) converts biomass to bio-crude, gas, solid residue and aqueous phase. Aqueous phase contains of bio-crude with relatively high amount of heteroatoms such as N, O, and S that made the bio-crude soluble in water and reduce ...

Hydrothermal liquefaction of biomass for production of diluents for bitumen transport [PDF]

, 2017
This study explores the hydrothermal liquefaction (HTL) of wood chips to bio-crude followed by upgrading to diluents, which are used to transport bitumen through pipelines. In this study, we considered a 2000 dry t day-1 plant capacity with two scenarios.

Hydrothermal liquefaction of sewage sludge: use of HCOOH and KOH to improve the slurry pumpability in a continuously operated plant

Heliyon
We studied the hydrothermal liquefaction (HTL) of digested sewage sludge (DSS) as model of waste biomass in batch and continuous reactors. HCOOH and KOH were used to improve the slurry pumpability.HTL experiments were conducted at the same kinetic ...

Hydrodeoxygenation of Black Liquor HTL Oil Model Compounds in Supercritical Water

Reactions
Black liquor, the side stream from Kraft pulping, is a promising feedstock for the production of renewable fuels via hydrothermal liquefaction (HTL). However, further upgrading of the black liquor HTL oil is required to reduce the oxygen content for fuel

Multiphase Numerical CFD Simulation of the Hydrothermal Liquefaction Process (HTL) of Sewage Sludge in a Tubular Reactor

Applied Sciences
This article presents multiphase numerical computational fluid dynamics (CFD) for simulating hydrothermal liquefaction of sewage sludge in a continuous plug-flow reactor. The discrete particle method (DPM) was used to analyze the solid particles’ interaction in liquid–solid high shear flows to investigate coupling computational fluid dynamics (CFD ...
