Biochar‐Based Catalysts for Selective Biofuel Upgrading: Mechanisms, Functions, and Synthesis Rules

open access: yesInternational Journal of Energy Research, Volume 2026, Issue 1, 2026.
Biomass‐derived fuels and bio‐oils are characterized by substantial quantities of oxygenated species and unstable compounds, which diminish fuel quality and necessitate upgrading before practical application. In this regard, biochar has garnered increasing attention as a catalyst and support because it is derived from renewable biomass resources, and ...

Hydrocarbon Fuels from Sequential Hydrothermal Liquefaction (HTL) of Lignite and Catalytic Upgrading of Crude Oil

open access: yesEnergy & Fuels
Lignite from Belchatów in Poland was converted to hydrocarbon fuels, particularly in the kerosene and diesel ranges, through sequential hydrothermal liquefaction (HTL) and hydrotreatment (HDT) of the obtained crude oil. Different HDT temperatures were investigated (from 350 °C up to 390 °C).

Hydrothermal liquefaction of microalgae for biofuel production: the recycling of nutrients from an aqueous solution after HTL

open access: yesIOP Conference Series: Materials Science and Engineering, 2019
Abstract Microalgae are an alternative source for the renewable biofuels production. One of the promising technologies of microalgae fuel production is the hydrothermal liquefaction (HTL) with obtaining bio-oil as the target product. We have carried out a number of experiments on the hydrothermal liquefaction the biomass of blue-green ...
