Integrated process for catalytic upgrading of hydrothermal liquefaction aqueous phase in the supercritical state

open access: yesFrontiers in Chemical Engineering
Hydrothermal liquefaction (HTL) is a waste agnostic process that leverages near-critical water to break down macromolecules, forming an energy-dense biocrude.

Upgrading of HydrofactionTM Biocrude Through Catalytic Hydrotreating

open access: yes, 2019
Alternative transportation fuels are critically required nowadays due to environmental concerns related to the rising of greenhouse gas emissions and the depletion of petroleum reserves. In this regard, advanced biofuels, commonly known as a second-generation biofuel, are gaining attention as promising candidates to replace the high polluting ...

Biomass to biocrude: A brief review of catalytic liquefaction

open access: yesBioResources
Biomass energy is the largest source of renewable energy, accounting for approximately 55% of global renewable energy consumption. Therefore, it holds great importance for the efficient utilization of biomass. Hydrothermal liquefaction (HTL) has been demonstrated to convert biomass into liquid biofuels, with physicochemical properties comparable to ...

Distillation of Biocrude Oil Converted from Biowaste via Hydrothermal Liquefaction [PDF]

open access: yes, 2016
Modern dependence on petroleum-based fuels contributes to the production of greenhouse gases and is not sustainable in the long run. One way to combat this issue is to develop alternative fuel sources such as biofuels derived from algae and food waste ...
