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 ...

Efficient Thermo‐Photocatalytic Methanation of Dilute CO2 via N‐Doped Carbon Encapsulated Co/CoO Nanoparticles

EcoEnergy, EarlyView.
A nitrogen‐doped carbon coated Co nanoparticles with CoO particles catalyst achieved 91.6% conversion efficiency of ultra‐dilute CO2 (∼400 ppm) with nearly 100% CH4 selectivity at 180°C under light irradiation. ABSTRACT Thermo‐photocatalytic CO2 methanation represents an attractive strategy for addressing global energy and environmental challenges ...

Hydrogen Production With Water Electrolysis Technologies: Advances, Performance, and Potential Use for Low‐Gradient Combustion

Energy Science &Engineering, EarlyView.
This review links recent advances in water electrolysis with hydrogen utilization in low‐gradient combustion systems. While hydrogen eliminates direct CO2 emissions, its environmental and economic benefits depend strongly on production pathways, system‐level efficiency, and NOx mitigation through MILD/FLOX/HiTAC combustion.
