Demonstrating Pilot-Scale Gas Fermentation for Acetate Production from Biomass-Derived Syngas Streams

Fermentation
Gas fermentation is gaining attention as a crucial technology for converting gaseous feedstocks into value-added chemicals. Despite numerous efforts over the past decade to investigate these innovative processes at a lab scale, to date, the evaluation of

Volumetric mass transfer and dilution rate as key parameters for sustainable industrial syngas fermentation to isopropyl alcohol: modeling and parametric assessment

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Synthesis gas fermentation is a promising route for the valorization of steel mill off‐gas and for replacing conventional fossil‐based isopropyl alcohol (IPA) production. A recent 120 L pilot‐scale study reported 85% gas conversion at 90% product selectivity and claimed a negative global warming potential (GWP) without detailed process design.

MODELLING AND SIMULATION OF FUELS PRODUCTION FROM SYNGAS

Studia Universitatis Babes-Bolyai Chemia, 2017
Syngas is a very important product, with a variety of uses; it may even become a primary source of fuel, and replace natural gas. This is because syngas has the building blocks to create all the products and chemicals currently generated in the ...

Potential contribution of biomass gasification‐based technology in energy transition: a technical review coupled with bibliometric studies

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Biomass gasification technology has been extensively researched around the world; however, there is a need to evaluate the current research landscape and evolutionary direction of research in the broader context of energy transition. A systematic bibliometric analysis of the Web of Science database was performed for articles that fall within ...

Sustainability Assessment of Circular Strategies in the Agri‐Food Industry: The Case of Olive Mills' By‐Product Valorization

Business Strategy and the Environment, EarlyView.
ABSTRACT This study integrates multidimensional sustainability indicators into a unified assessment approach to evaluate circular strategies in agri‐food industry businesses. This methodological approach is applied to empirically examine the case of the olive oil industry's by‐product valorization.

Organophotoredox/Cobalt‐Catalyzed Retro‐Hydroformylation of Aldehydes

ChemistryEurope, EarlyView.
A new photoredox/cobalt retro‐hydroformylation is developed. This one‐pot two‐step process involves the in situ formation of the corresponding 1,4‐dihydropyridine as key intermediate. Under mild reaction conditions, alkenes are efficiently produced from a wide range of aliphatic α‐monosubstituted aldehydes, with high functional‐group tolerance.

Risk assessment of syngas pipeline leakage based on a Dynamic Bayesian Network

Emergency Management Science and Technology
The syngas pipeline serves as the primary carrier for syngas exported from the coal gasification furnace, is vulnerable to corrosion and erosion from the transported medium, and is prone to leakage due to long-term high-pressure operation.
