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

open access: yesBiofuels, 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.

Study on the evolution characteristic of intermediate during the pyrolysis of oil shale

open access: yes, 2017
The pyrolysis of oil shale is a complex process including a myriad of chemical reactions. A widely approved understanding suggests a two-step decomposition process for oil shale pyrolysis, considering bitumen as the intermediate product. In this study,

Artificial Intelligence–Driven and Digital Practices for Circular Business and Finance: Insights for Advancing Hubs for Circularity

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The emerging concept of Hubs for Circularity (H4Cs) presents an opportunity to create collaborative, self‐sustaining regional industrial ecosystems that drive circular economy transitions at scale. However, the operationalisation of H4Cs faces financial, organisational and data‐driven challenges.

Carbon‐Embedded Fe‐Cu Composite Oxide Nanoparticles Derived From Spindle‐Shaped Bimetallic MOFs for Selective Oxidation of Methane

open access: yesCarbon and Hydrogen, EarlyView.
Fe3Cu1/C (CuFe5O8) was synthesized by high‐temperature carbonization of FexCuyBDC MOF, which exhibited excellent catalytic performance for methane selective oxidation at 80°C. The synergistic effect between Cu and Fe in the derived Fe3Cu1/C (CuFe5O8) composite oxide inhibits deep oxidation compare to Fe/C (Fe3O4), and the reaction proceeds via a free ...

Evaporation of pyrolysis oil: Product distribution and residue char analysis

open access: yesAIChE Journal, 2010
AbstractThe evaporation of pyrolysis oil was studied at varying heating rates (∼1–106°C/min) with surrounding temperatures up to 850°C. A total product distribution (gas, vapor, and char) was measured using two atomizers with different droplet sizes.
