The characterization of products produced from hydrothermal liquefaction of algal biomass is helpful to better understand the effect of different kinds of raw materials on the properties of the product fractions. The data presented in this article are related to the research article entitled "Integration of hydrothermal liquefaction and supercritical water gasification for the improvement of energy recovery from algal biomass" (Duan et al., 2018) [1]. In this data article, the compositions of gaseous products produced from hydrothermal liquefaction of eight different algae feedstocks at 350 °C for 60 min were analyzed by gas chromatography. The molecular and elemental compositions of the crude bio-oils produced from hydrothermal liquefaction of eight different algae feedstocks at 350 °C for 60 min were analyzed by comprehensive two-dimensional gas chromatographytime-of-flight mass spectrometry and organic elemental analyzer. The color of aqueous phases before and after they were subjected to supercritical water gasification was recorded by a high-resolution camera.

Exploring the catalytic hydrothermal liquefaction of Namibian encroacher bush.

Sci Rep

January 2025

Process and Energy Department, University of Technology of Delft, Leeghwaterstraat 39, 2628 CB, Delft, The Netherlands.

An urgent ecological issue is the threat posed by invasive species, which are becoming more widespread especially in Africa. These encroachments damage ecosystems, pose a threat to biodiversity, and outcompete local plants and animals. This article focuses on converting Acacia Mellifera from Namibia, commonly known as encroacher bush (EB) into high-quality drop-in intermediates for the chemical and transport industry via hydrothermal liquefaction (HTL).

Article Synopsis
  • The study analyzes the economic feasibility of producing biocrude through hydrothermal liquefaction (HTL) at decentralized plants linked to wastewater treatment facilities.
  • The base case is based on a Danish WWTP serving 150,000 population equivalents, with results showing operational expenses as the largest cost factor.
  • Biocrude production is estimated at 94 kg/h with a minimum selling price ranging from 0.9 to 1.8 €/kg, depending on the plant size, while factors such as biocrude yield and labor costs significantly impact pricing.

Analysis on Degradation Mechanism and Product Recycle of Ex-service Wind Turbine Blades by Hydrothermal Liquefaction.

ACS Omega

November 2024

Key Laboratory of Energy Thermal Conversion and Control, School of Energy and Environment, Southeast University, Nanjing 210096, P. R. China.

The recycling of ex-service wind turbine blades (EWTBs) presents a significant challenge for the future. Hydrothermal liquefaction (HTL) has emerged as a promising approach for the recovery of resins and glass fibers (GFs) from EWTBs. This study offers a comprehensive analysis of the separation mechanisms and product characteristics under the catalytic effect of an acidic medium during the HTL tests.

Organosolv-derived lipids from hemicellulose and cellulose, and pre-extracted tannins as additives upon hydrothermal liquefaction (HTL) of spruce bark lignins to bio-oil.

BMC Biotechnol

November 2024

Biochemical Process Engineering, Division of Chemical Engineering, Department of Civil, Environmental and Natural Resources Engineering, Luleå University of Technology, Luleå, SE-971 87, Sweden.

Article Synopsis
  • The study explores using spruce bark, a largely untapped resource, to produce bio-oil, a renewable energy source, as a response to rising global temperatures and petroleum waste issues.
  • It utilizes a process called hydrothermal liquefaction, enhancing bio-oil quality by extracting polysaccharides and converting them into lipids with the help of specific microorganisms.
  • Results showed that pre-extracting tannins and modifying the heating rates in the production process improved the energy content and yield of the bio-oil while reducing its oxygen content.

Renewable Fuels and Chemical Recycling of Plastics via Hydrothermal Liquefaction.

Acc Chem Res

December 2024

Penn State University, Chemical Engineering Department, University Park, Pennsylvania 16802, United States.

Article Synopsis
  • Hydrothermal liquefaction (HTL) is a process that converts various biomass types into renewable bio-oil through reactions in hot, compressed water, producing additional gas and solid products.
  • The process retains a substantial amount of chemical energy, recovering around 70-80% of it in an oil that weighs only 20-50% of the original biomass, though the bio-oil often requires further upgrading to be usable as fuel.
  • HTL can also convert different plastics into oil, achieving high yields with certain types while being less effective with others, indicating its potential for recycling and valorizing post-consumer plastic waste.
