Pyrolysis of biogas for carbon capture and carbon dioxide-free production of hydrogen

Abstract

Methane pyrolysis is considered an auspicious approach for large-scale hydrogen production and simultaneous carbon capture, hereby contributing to a decarbonization of the chemical industry. While commonly pure methane or natural...

Autothermal Oxidative Coupling of Methane over Pt/Al2O3 Catalysts Doped with Rare Earth Oxides

“…The simplest hydrocarbon, methane (CH 4 ), which nowadays originates not only from fossil natural gas [1], but also from fermentation of biomass [2] and power-to-gas processes using renewable energy [3], plays a key role in chemical industry. It is of great interest for a variety of different applications such as (bio-)methane pyrolysis [4][5][6], dry reforming [7,8], or catalytic partial oxidation (CPOX) for syngas production [9,10]. The main obstacle for any of these processes is the comparably strong C-H bond of the CH 4 molecule, necessitating either high energy input or suitable catalysts for C-H bond scission [11].…”
