Abstract

Abstract

En 中文
• The outlet from the first reactor is only methane and carbon dioxide. • In the absence of external hydrogen syngas can be cleaned and sold as biogas. • Two-reactor setup boosts methane purity to 95% from syngas. • Series configuration ensures 100% carbon monoxide conversion. • Methane yield rises to 6.13 Nm³·m⁻³·d⁻¹ using two thermophilic reactors. • Series design offers flexibility for variable hydrogen supply scenarios.
