“…The BioMates phase of HDT bio-oil was blended at three blending ratios (10%, 20% and 30% per volume BioMates) with LCO that was provided from a BP refinery, none of which contained any additives. LCO was selected via a detailed preceding study [21,23], as the most compatible candidate from a miscibility perspective for co-processing with BioMates, as it consists of more polar molecules like aromatics, similarly to BioMates, therefore sharing similar challenges as a feedstock for hybrid fuel production and also presented very good miscibility with the BioMates. The addition even of 10% per volume BioMates in neat LCO has caused a color change of the sample, as BioMates is darker than LCO (Picture 2).…”

“…The aim of this work is to show the extent of the co-processing potential. LCO was selected as appropriate petroleum feed candidate for co-hydroprocessing with the BioMates, based on an author's previous work focusing on the miscibility of Bio-Mates with several refinery intermediates and the compatibility with their fuel characteristics [21,22]. According to this study, the binary blend of the BioMates and LCO showed increased homogeneity, while fuel characteristics such as density, viscosity, elemental composition, refractive index and boiling point distribution exhibited certain similarity.…”

The co‐processing of biocrude in petroleum refineries is viewed as an economical and practical pathway to produce low‐carbon fuels. A major challenge to co‐processing is the poor miscibility of biocrudes with petroleum due to their high levels of oxygen. This study investigated the mild hydrodeoxygenation of biocrude derived from hydrothermal liquefaction (HTL) of agriculture waste as a means to enhance its miscibility with petroleum vacuum gas oil (VGO). Blending compatibility tests were performed to identify the extent of deoxygenation required to achieve blending of 10 wt% treated biocrude in VGO. The highest oxygen removal (~72%) was achieved by increasing the temperature in three steps (240, 280, and 300 °C), with pressure kept at 1400 psi and a catalyst‐to‐feed ratio of 0.19 g g−1. Under such conditions, the hydrotreated biocrude was found to be miscible in VGO and the resulting blend was stable over 7 days. The hydrotreated biocrude products were characterized using nuclear magnetic resonance to identify changes in oxygenated compound classes, such as carboxylic acids, alcohols, ethers, carbohydrates, carbonyls, and phenolics. Carboxylics and phenolics were identified as important contributors to the miscibility of the biocrude. In further testing, two 10 wt% blends of hydrotreated and raw biocrude in VGO were co‐processed through hydrotreating. These supplementary tests confirmed that the hydrotreated biocrude performed better in terms of catalytic activity than the raw biocrude. © 2021 Her Majesty the Queen in Right of Canada.

“…While it was previously thought that the extraction of chemicals from bio-oil was not advantageous due to low specific chemical contents and the high economic cost of separation processes [116], recent works suggest that it is possible to obtain more componentspecific bio-oils. Additionally, even the co-processing of bio-oil may still require bio-oil to be upgraded [176], thus raising the question whether separation processes are that disadvantageous when compared to upgrading.…”

Bio-Oil: The Next-Generation Source of Chemicals

Bio-oil, although rich in chemical species, is primarily used as fuel oil, due to its greater calorific power when compared to the biomass from which it is made. The incomplete understanding of how to explore its chemical potential as a source of value-added chemicals and, therefore, a supply of intermediary chemical species is due to the diverse composition of bio-oil. Being biomass-based, making it subject to composition changes, bio-oil is obtained via different processes, the two most common being fast pyrolysis and hydrothermal liquefaction. Different methods result in different bio-oil compositions even from the same original biomass. Understanding which biomass source and process results in a particular chemical makeup is of interest to those concerned with the refinement or direct application in chemical reactions of bio-oil. This paper presents a summary of published bio-oil production methods, origin biomass, and the resulting composition.
