A combined sol–gel/solid‐state approach was developed to integrate GeSe2 with a “volcanic‐rock”–like carbon framework (C). C incorporation reactivates the otherwise irreversible intermediates Na2Ge2Se5 and Na2GeSe3, thereby suppressing irreversible Na+ consumption.

Converting biomass‐derived syngas into value‐added fuels and chemicals offers a promising route toward carbon neutrality, yet unfavorable H2/COx ratios, elevated CO2 levels, and trace impurities pose persistent obstacles. This review examines strategies spanning syngas conditioning, impurity‐tolerant catalyst development, and integrated process design,

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

Catalytic Oxidation of CO and VOC in Flue Gas of Coffee Roasting Machines
Platinum‐coated cordierite monoliths effectively oxidized CO and VOC in coffee roasting exhaust with higher Pt loadings lowering light‐off temperatures. Scaled up 90 g/ft3 catalyst in a 5 kg roaster achieved 96% CO and around 78% VOC conversion at 350°C, highlighting stable operation requires flue gas temperatures ≥350°C.

Comparative Assessment of Methanol Production Pathways From Steel Mill Gases
This publication reviews the process concepts and assessments for converting steel mill gases into sustainable methanol, focusing on energy efficiency, and the regulatory framework. From an energy perspective, the production of methanol from BOFG and H2 separated from coke oven gas is of particular interest.

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 ...

Process Gas Transitions in the Steel Industry—Planning Corridors for Chemical Utilization
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.
