Kinetics Analysis of the Syngas Fermentation to Produce Acetic Acid from Cardoon Residual Biomass

Chemical Engineering Transactions, 2022
Lignocellulosic biomass can be converted to biofuels and biochemicals through several process pathways: pretreatment and sugars fermentation, thermochemical conversion (pyrolysis, gasification) and syngas synthesis.

Synthesis Gas from Waste Plasma Gasification for Fueling Lime Kiln

Chemical Engineering Transactions, 2014
High fuel price coupled with the requirement to reduce the use of fossil fuels has created the interest to use low calorific value gases. Fuelling lime kilns with renewable fuels to displace fossil fuel is not a new idea and has been subject of many ...

Single-pass transformation of syngas into ethanol with high selectivity by triple tandem catalysis

Nature Communications, 2020
Synthesis of ethanol from non-petroleum carbon resources via syngas (a mixture of H2 and CO) is an important but challenging research target. The current conversion of syngas to ethanol suffers from low selectivity or multiple processes with high energy ...

Syngas biomethanation: effect of biomass-gas ratio, syngas composition and pH buffer

Bioresource Technology, 2021
The concept of syngas biomethanation is attractive, however, it still needs improvement in optimizing the operational conditions. In the present study, syngas fermentations under different carbon monoxide (CO), carbon dioxide (CO2) and hydrogen (H2) compositions were conducted under two different biomass-gas ratio (BGR) systems. The results showed that

Iridium Oxide Inverse Opal Anodes with Tailored Porosity for Efficient PEM Electrolysis

Advanced Functional Materials, EarlyView.
The synthesis of Iridium‐based Inverse Opals (Ir‐IO) is reported as electrocatalyst for Proton exchange membrane water electrolysis (PEM‐WE). Using the developed protocol it produces highly porous materials consisting either of metallic, oxidic Iridium or a combination thereof with large surface areas.

Achieving Stable Paired Electrolysis of Captured CO2 and 5‐Hydroxymethylfurfural (HMF) via Tuning Anolyte Composition and Anode Surface

Advanced Functional Materials, EarlyView.
Highly stable paired electrolysis of CO2 and biomass‐derived alcohol (HMF) is achieved by replacing conventional alkaline electrolytes with a tailored triethylamine‐carbonate buffer and anion‐conducting ionomer coatings. This configuration effectively mitigates electrolyte degradation and pH instability typically encountered in alkaline CO2 ...
