AVALIAÇÃO DA EFICIÊNCIA DE FILTROS ALTERNATIVOS PARA BIOGÁS DA BIODIGESTÃO ANAERÓBIA DE VINHAÇA DE ETANOL

O estudo avaliou a eficiência da purificação do metano (CH₄) produzido a partir da vinhaça da produção de álcool, utilizando esterco bovino como inoculante em diferentes concentrações (5% a 25%) em biodigestores do tipo indiano. O processo ocorreu em cinco biodigestores de PVC operados em batelada, com controle de temperatura em 35°C e ajuste de pH com bicarbonato de sódio.

Integration of biogas dry methane reforming and electrolysis: An efficient pathway for green hydrogen production

The study shows that green hydrogen can be produced from biogas using DMR combined with SOEC or PEMEC electrolysis. The DMR–SOEC system is the most efficient (74.62%) due to waste heat recovery.Overall, SOEC integration is the best option for efficient hydrogen production.

Exploring novel biogas-to-bio methanol conversion: Exergy-driven hybrid pathways for enhanced methanol yield

The study evaluates biogas conversion into bio-methanol using two process configurations: direct steam methane reforming (SMR) and a CO₂ removal route followed by reforming.

Brazil’s Biogas–Biomethane Production Potential: A Techno-Economic Inventory and Strategic Decarbonization Outlook

The study quantifies Brazil’s technical potential for biogas production from agro-industrial, livestock, and urban residues, estimating about 80–85 billion Nm³/year of biogas, which could be converted into ~43–45 billion Nm³/year of biomethane or ~168–174 TWh/year of electricity.
