Unbiased Reaction Network Exploration of C–C Coupling in Methane Dehydroaromatization Over Mo‐ZSM‐5
Chemistry – A European Journal, EarlyView.Automated reaction route mapping reveals distinct methane coupling pathways over mono‐ and dinuclear Mo carbide species in ZSM‐5. Mononuclear [MoC]2+ selectively forms desorbable C2H4, whereas dinuclear [Mo2C2]2+ promotes strongly adsorbed C3/C4 intermediates linked to coke formation.

Coke Decomposition Kinetic Model of Spent Hydrodesulfurization Catalysts [PDF]
Journal of Applied Sciences and NanotechnologyRecycling residue hydrodesulfurization (HDS) catalysts is essential due to frequent deactivation. Petroleum coke's high ignition temperature and complex combustion behavior stem from its graphite-like structure and low volatile matter.

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.

Process Gas Transitions in the Steel Industry—Planning Corridors for Chemical Utilization
Chemie Ingenieur Technik, EarlyView.Scenario‐based planning corridors link route‐ and pace‐dependent steelworks off‐gas availability (BFG, BOFG and SAFG) to a 1000 mtpd methanol demand over 2030–2060, revealing pace‐limited BFG concepts and route/site‐size limits for CO‐rich operation and motivating early CO2 tie‐ins as retrofit‐friendly safeguards.
