Techno‐Economic Analysis of Methanol Production From Steel Mill Gases

Chemie Ingenieur Technik, EarlyView.
A techno‐economic analysis for the synthesis of methanol from steel mill gases is carried out. Four different process concepts are defined and analyzed. The analysis yields levelized cost of methanol estimates between €1130 and €1419 t−1. Sensitivity analyses identify hydrogen production as the largest contributor to cost.

From Potentiostatic to Galvanostatic Control in Pulsed Electrochemical CO2 Reduction to Ethylene

Chemie Ingenieur Technik, EarlyView.
A two‐gap flow cell with three‐electrode configuration bridges the gap between H‐cells and industrial zero‐gap electrolyzers. Using ethylene‐selective CO2 reduction on copper as a model reaction, galvanostatic operation shows greater stability than potentiostatic control, whereas charge‐controlled pulsed protocols enable C2H4 selectivity under ...

Laminar Burning Velocity of Ammonia‐Hydrogen Mixtures Predicted by Machine Learning

Chemie Ingenieur Technik, EarlyView.
Ammonia–hydrogen blends aid defossilization, but slow combustion kinetics require complex modeling. Although chemical kinetic modeling is computationally expensive, machine learning surrogates offer fast predictions. This study trained GPR, DT, and ANN models on 1445 experimental points.

A study of Ni‐Co/CeO2 catalyst derived from metal–organic framework for dry reforming of methane

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The efficacy of cobalt‐doped, MOF‐derived catalysts for dry reforming of methane (DRM) was examined. The focus was on the influence of varying nickel and cobalt molar ratios on catalytic performance. Three catalysts with Ni:Co ratios of 1:1, 1:0.5, and 0.5:1, were synthesized and tested with cerium oxide as a constant support. The DRM reaction

Random forest regression for catalyst performance prediction and validation of tri‐reforming of methane (TRM)

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Carbon dioxide‐reduced hydrogen can be synthesized through various methods such as dry‐reforming (DRM), steam reforming (SMR), and partial oxidation (POX). Tri‐reforming of methane (TRM) is a promising technology which combines all the above‐mentioned processes for the simultaneous production of hydrogen and syngas with high energy efficiency.
