Composition of Purified CO2 From Steel Mill Processes—A Classification and Analytical Comparison With Commercial CO2

open access: yesChemie Ingenieur Technik, EarlyView.
Due to the severe catalyst poisoning effect of certain trace components, the purity of CO2 is the main attribute to qualify it as syngas for further downstream processes. This study uses PTR–MS to investigate the trace components of the CO2 produced within the Carbon2Chem project.

Techno‐Economic Analysis of Methanol Production From Steel Mill Gases

open access: yesChemie 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.

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

open access: yesChemie 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

open access: yesThe 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

A High-Temperature, High-Speed, Oil-Free Syngas Compressor for Small-Scale Combined Heat and Power

open access: yes
For low-emission, small-scale combined heat and power generation, integrating a biomass gasifier with a downstream solid oxide fuel cell system is very promising due to their similar operating conditions in terms of temperatures and pressures. This match

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

open access: yesThe 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.

Microwave‐assisted catalytic pyrolysis of textile wastes: Synergistic effects and product characteristics

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study examines the microwave‐assisted catalytic pyrolysis (MACP) of individual and blended textiles (cotton, polyester, nylon 6) using ZnO and a ZnO/natural zeolite catalyst. In a custom‐built microwave reactor operated at 500°C, 1 kW power, and a 15‐min residence time, textile wastes were pyrolyzed.

Experimental methods in chemical engineering: Temperature‐programmed oxidation—TPO

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Temperature‐programmed oxidation (TPO) probes the oxidative capacity and redox properties of solid materials—catalysts, metal oxides, perovskites, and carbonaceous deposits. It identifies coke type, distribution, and reactivity. TPO instruments pass an oxidizing gas (diluted O2$$ {\mathrm{O}}_2 $$, air, or less commonly N2O$$ {\mathrm{N}}_2 ...
