H2 Production from Ammonia Borane: Integrating Experiments, Computational Fluid Dynamics, and Statistical Analysis for Predicting and Optimizing Process and Reactor Design

ChemCatChem, EarlyView.
Ammonia borane is considered a great hydrogen carrier, and when hydrolyzed, it can generate 3 moles of H2. This study highlights the combination of experimental and computational work, such as modeling and statistical analysis, that enables future experimentation by focusing on the parameter with the most profound effect on maximum H2 yield.

Dual-fuel combustion in a tangential PC-fired boiler of type OP-230 – computational simulations

E3S Web of Conferences, 2018
Syngas co-firing in coal fired boilers can be one of the prospective technologies which may help to retrofit some of still functioning older boilers. This study focuses on the results of CFD simulations of wood biomass-derived syngas co-firing with coal ...

A Reexamination of CO2 Reduction with Fe2S2 Hydrogenase Mimics: Lessons in Using a Hydrogen Evolution Reaction Catalyst for CO2 to Formate Catalysis

ChemElectroChem, EarlyView.
Combining cyclic voltammetry, infrared spectroelectrochemistry, and density functional theory methods, the reduction of CO2 by an [FeFe] hydrogenase mimic was examined. Despite its ability to form stable reduced hydride species, this catalyst does not selectively reduce CO2 to HCOO− under the tested conditions.

Electrified Carbon Cycling for Neutralizing the Steelmaking Industry

Carbon Energy, EarlyView.
Steelmaking is energy‐intensive and heavily reliant on fossil fuels, contributing significantly to global carbon emissions. Developing a renewable processing approach compatible with existing infrastructure is urgent. Electrified carbon cycling based on CO2RR converts CO2 into CO, reducing coke usage and CO2 emissions, thus enabling carbon‐neutral ...

Hydrogen from Biogas: Dynamic Modeling of an Integrated Shift Reactor

Chemie Ingenieur Technik, EarlyView.
A dynamic, two‐dimensional shift reactor model for the production of hydrogen from biogas is presented. This shift reactor enables the preheating of the biogas feed and, in parallel, reduces fixed‐bed temperatures, resulting in increased hydrogen yields. The model is validated with measurement data from a pilot biogas steam reforming plant.

Development and Validation of a Laboratory‐Scale Methanol Synthesis Mini‐Plant and Digital Twin Simulation

Chemie Ingenieur Technik, EarlyView.
A methanol mini‐plant and its digital twin were developed to study flexible feedstocks, reactant recycling, and product condensation. Experimental results show good agreement with simulations, allowing systematic investigation of process parameters. Tests with biomass‐derived syngas demonstrated the feasibility of industrial COx sources.

Effect of syngas recirculation in the pyrolysis zone on the rice husk gasification process using the downdraft reactor

Case Studies in Thermal Engineering
As one of the world's largest rice producers, Indonesia has an abundance of rice husk as a byproduct of rice milling. Rice husks were utilized to examine downdraft gasification with syngas recirculation system.

A catalytic sites contiguity study on atomically‐dispersed ZnO‐Cu/SiO2 catalysts to improve methanol formation from CO2 hydrogenation

The Canadian Journal of Chemical Engineering, EarlyView.
The synergistic interaction between Cu0/Cu+ and atomically dispersed ZnO (ADZn) sites enhances methanol production. The contiguity of these sites influences the methanol synthesis from CO2 hydrogenation. Abstract Cu‐ZnO‐based catalysts are commonly used in research on catalytic carbon dioxide (CO2) hydrogenation for methanol (MeOH) synthesis. This work
