Numerical Analysis of Steam-methane Reforming Reactio for Hydrogen Generation using Catalytic Combustion

, 2013
A steam reformer is a chemical reactor to produce high purity hydrogen from fossil fuel. In the steam reformer, since endothermic steam reforming is heated by exothermic combustion of fossil fuel, the heat transfer between two reaction zones dominates ...

Does EU Taxonomy Alignment Reduce Corporate Emissions? Evidence From Nordic Firms

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This paper investigates whether EU Taxonomy alignment is associated with lower corporate emissions, using 982 firm‐years from 358 Nordic firms (2022–2025). Extending targeted transparency theory, the study develops a signal‐quality framework under which a mandated classification is informative only if it satisfies signal relevance, signal ...

Sustainable Hydrogen Production by Glycerol and Monosaccharides Catalytic Acceptorless Dehydrogenation (AD) in Homogeneous Phase

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Sustainable hydrogen production can be obtained from hydogen‐rich biomass‐derived organic molecules through Acceptorless Dehydrogenation (AD) reactions. Glycerol and sugars are available in large quantities from industry and can be successfully used as substrates in AD protocols, in the presence of tailored, selective, easily tunable and thermally ...

The effects of oxygen carrier, CO2/H2O ratio, temperature, and CO2 content in chemical looping reforming of biogas: A parametric experimental study

Applications in Energy and Combustion Science
The transition toward low-carbon energy systems highlights the potential of biogas valorization as a renewable route for hydrogen generation. Conventional reforming processes are limited by catalyst deactivation caused by coke formation and sintering ...

Molten‐Salt‐Mediated Chemical Looping Oxidative Dehydrogenation of Ethane with In‐Situ Carbon Capture and Utilization

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
A sustainable alternative to steam cracking, the molten‐salt‐mediated oxidative dehydrogenation (MM‐ODH) of ethane (C2H6) in Li2CO3‐Na2CO3‐K2CO3 (LNK) couples thermal cracking with melt‐mediated CO2 capture to realize commercially competitive C2H4 and CO yields. LNK composition strongly influences MM‐ODH process outcomes.

Temperature‐Dependent Kinetics of Plasma‐Based CO2 Conversion: Interplay of Electron‐Driven and Thermal‐Driven Chemistry

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
The transformation of CO2 into chemical building blocks is essential for a net‐zero energy future. Plasma‐chemical processing offers promising potential to achieve this. Here, we explore a temperature‐dependent plasma‐chemical reaction mechanism, revealing a shift from electron‐driven to thermal‐driven CO2 conversion regimes.
