CO2 Utilization

CO2 reforming of CH4
Using coke oven gas
CH4 + CO2 → 2H2 + 2CO

(∆H = +286 kJ/mol): Endothermic reaction

•
Utilizes 2 major greenhouse gases to produce H2 (CCU technology)
•
CH4 & CO2: Stable molecules → Requires high reaction temperature
•
High reaction temperature → Metal sintering → Deactivation
•
Large amount of carbon sources → Vulnerable to coking
[Side reactions]
-
Methane decomposition
CH4 → C + 2H2, ∆H = +75 kJ/mol
-
Boudouard reaction
2CO → C + CO2, ∆H = –172 kJ/mol
•
Development of stable catalyst with strong sintering- and coke-resistance is required
