First Operation Results of a Methanol Demonstration Plant With Real Steel Mill Gases

Chemie Ingenieur Technik, EarlyView.
A demonstration plant with industrial setup regarding length, diameter, boiling water cooling system and gas recycle was initially operated with cleaned blast furnace gas and compared with earlier experiments with bottle gases. Dynamic disturbances from the steel mill and gas cleaning unit were noticed and could be compensated by the control system ...

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.

Impact of Trace Water on the Macroscopic Activity of Commercial Ammonia Cracking Catalysts Under Process‐Relevant Conditions

Chemie Ingenieur Technik, EarlyView.
This study evaluates how small water impurities—typical in ammonia cracking feedstock—affect catalyst performance at elevated pressures and temperatures. By decoupling permanent degradation from reversible inhibition, the findings highlight trace water as a significant factor for reliable catalyst screening and industrial ammonia cracking scale‐up ...

Developments in the EU Emissions Trading System and Their Effects on CCU Pathways

Chemie Ingenieur Technik, EarlyView.
From an engineer's perspective, the development of the European emissions trading system is analyzed. Difficulties for the use of carbon dioxide, particularly from mixed carbon sources, can be traced back to regulations whose effects might be resolved in the upcoming EU ETS revision. ABSTRACT The analysis presented in this article focuses on provisions

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

The 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

The 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 ...
