Bio-Oil Hydrotreatment for Enhancing Solubility in Biodiesel and the Oxydation Stability of Resulting Blends

Frontiers in Chemistry, 2018
The major challenge for the pyrolytic conversion of lignocellulosic materials into crude bio-oil is the poor quality of the final product. Several strategies (addition of solvents, production of emulsions, and extraction with biodiesel) have been studied

Unveiling opportunities and challenges for a circular approach to macaúba biorefining: a technological roadmap

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The macaúba fruit, native to tropical and subtropical regions, has received considerable attention in recent years as a promising raw material for the production of advanced biofuels in Brazil. However, the development of large‐scale biomass requires overcoming significant challenges, such as designing circular biorefineries.
