Abstract
En 中文
• Aspen Plus model developed for co-gasification of duckweed and water hyacinth. • Hydrogen-rich syngas (41.15%) achieved using invasive aquatic feedstocks. • ER and temperature identified as key syngas influencers via RSM-ANOVA. • Maximum CGE (94.79%) and CCE (86.41%) obtained at optimized conditions. • Promotes SDG 7 through waste valorization and carbon-efficient energy.
