Lignocellulose Liquefaction to Biocrude: A Tutorial Review [PDF]
ChemSusChem, 2018 AbstractAfter 40 years of research and development, liquefaction technologies are now being demonstrated at 200–3000 tons per year scale to convert lignocellulosic biomass to biocrudes for use as heavy fuel or for upgrading to biofuels. This Review attempts to present the various facets of the liquefaction process in a tutorial manner.

Harnessing Activated Sludge for the Treatment of Hydrothermal Liquefaction Wastewater: A Proof-of-Concept Study. [PDF]
Water Environ ResActivated sludge cultivation for sewage sludge HTL wastewater treatment was optimized using high temperature incubation, nutrient supplementation, high dilution factor, and overliming pretreatment. Up to 91.2% sCOD removal was achieved, with kinetics analysis confirming enhanced degradation rates under treatment optimization.

Fuel, 2023 Hydrothermal liquefaction (HTL) process of protein-rich biomass produces biocrude with a high nitrogen content that hinders its use as a biofuel intermediate. Nitrogen compounds in the biocrudes are mainly present as fatty acid amides (FAAs) and nitrogen-containing polycyclic aromatic compounds (NAs), having different hydrodenitrogenation reactivity ...

Fractional distillation of hydrothermal liquefaction Biocrude [PDF]
, 2021 This thesis describes fractional distillation as an upgrading method for improving the quality of hydrothermal liquefaction (HTL) biocrude as a green-based biofuel. Firstly, as a part of the biomass to fuel pathway, aqueous phase recycling in the HTL process increased the yield of biocrude production and reduced the nitrogen content.

Thermodynamic analysis of algal biocrude production [PDF]
Energy, 2012 Abstract Although algal biofuels possess great potential, profitable production is quite challenging. Much of this challenge is rooted in the thermodynamic constraints associated with producing fuels with high energy, low entropy, and high exergy from dispersed materials.

Biomass-to-biocrude on a chip via hydrothermal liquefaction of algae [PDF]
Lab on a Chip, 2016 Hydrothermal liquefaction uses high temperatures and pressures to break organic compounds into smaller fractions, and is considered the most promising method to convert wet microalgae feedstock to biofuel. Here, we present a microfluidic screening platform to precisely control observe, and analyze this process at high temperature and pressure.

Biocrude suitability for petroleum refineries
, 1988 Technologies are now being developed that could produce crude oil from biomass, making available an alternative fuel source as petroleum supplies dwindle and prices rise. If the existing infrastructure for transporting and refining petroleum could be used for biocrude, the transition from petroleum would be smoother and less costly.

Biocrude production by hydrothermal liquefaction of olive residue [PDF]
International Journal of Sustainable Development and Planning, 2016 Hydrothermal liquefaction (HTL) converts biomass into a crude bio-oil by thermally and hydrolytically decomposing the biomacromolecules into smaller compounds. The crude bio-oil, or biocrude, is an energy dense product that can potentially be used as a substitute for petroleum crudes.

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 3, May/June 2026.ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...
