Interfacial Electronic Coupling in the GeSe2/Volcanic‐Rock–Like Carbon Framework Activates Reversible Intermediate Conversion for High‐Rate Sodium Storage

Carbon Energy, EarlyView.
A combined sol–gel/solid‐state approach was developed to integrate GeSe2 with a “volcanic‐rock”–like carbon framework (C). C incorporation reactivates the otherwise irreversible intermediates Na2Ge2Se5 and Na2GeSe3, thereby suppressing irreversible Na+ consumption.

An Experimental Study on the Effects of Pre-Chamber Geometry on the Combustion Characteristics of Ammonia/Air Mixtures Using Turbulent Jet-Post Spark Ignition Strategy

Energies
As a carbon-free fuel, ammonia faces challenges in engine applications due to its low flame propagation speed and high ignition energy. The pre-chamber turbulent jet-post spark ignition strategy (TJ-PSI) has been proven effective in accelerating the ...

Challenges of Bio‐Syngas Conversion to High‐Value‐Added Liquid Chemicals and Fuels via COx Hydrogenation

Carbon Energy, EarlyView.
Converting biomass‐derived syngas into value‐added fuels and chemicals offers a promising route toward carbon neutrality, yet unfavorable H2/COx ratios, elevated CO2 levels, and trace impurities pose persistent obstacles. This review examines strategies spanning syngas conditioning, impurity‐tolerant catalyst development, and integrated process design,

Global and Detailed Calculation of Tube Wall Temperature in a Process Furnace Steam Superheater

Chemie Ingenieur Technik, EarlyView.
This study presents a comparison between an iterative global model and multiple approaches to a new non‐iterative model with the purpose of predicting tube wall temperature of a superheater. The results show that the non‐iterative method achieves sufficient accuracy while improving the prediction of local temperature distribution and better ...

Prospective LCA of E‐Methanol Along the Transformation of Steel Industry

Chemie Ingenieur Technik, EarlyView.
The environmental effects of change in steel production route on e‐methanol production are analyzed as they shift from blast furnace route to direct reduction route. Specific hydrogen demand reduces, as do the avoided CO2 emissions. E‐methanol's overall carbon footprint stays in a narrow range of −1 to −1.1 kg‐CO2‐eq./kg‐methanol.

Selective Non‐Catalytic Reduction of NOx in the Exhaust Gas of Small Wood Gasification Boilers

Chemie Ingenieur Technik, EarlyView.
Kinetic studies of the SNCR reaction were conducted to investigate NOx reduction in the exhaust gas of small‐scale wood gasification boilers. Both the experimental results and the derived global kinetic model indicate that SNCR can achieve a significant reduction in NOx emissions under typical operating conditions. ABSTRACT The gas‐phase reaction of NO

Analysis of the Regulatory Framework for the CCU Technology

Chemie Ingenieur Technik, EarlyView.
ABSTRACT Carbon capture and utilisation (CCU) is increasingly considered an important technology for achieving climate neutrality within the German and European legal framework. Recent developments, particularly the Carbon Dioxide Storage and Transport Act (KSpTG), aim to enable CO2 transport infrastructure and cross‐sector carbon management systems ...
