Hydrogen-rich gas production from the gasification of biomass and hydrothermal carbonization (HTC) aqueous phase
In this paper, we investigated the characteristics of the aqueous phases (APs) derived from different agricultural wastes (e.g., peanut and wheat straws) and the co-gasification of cotton stalk (CS) and APs. The functional groups and pyrolysis behavior of the APs at different hydrothermal temperatur...

Zusammenfassung: | In this paper, we investigated the characteristics of the aqueous phases (APs) derived from different agricultural wastes (e.g., peanut and wheat straws) and the co-gasification of cotton stalk (CS) and APs. The functional groups and pyrolysis behavior of the APs at different hydrothermal temperatures (160 °C–300 °C) were analyzed by FTIR and TG-FTIR. The hydrothermal temperatures deeply influenced the evolution of the main gaseous products. Through the experiment and analysis of the co-gasification of CS and APs, it introduced that the co-gasification syngas product was dominated by hydrogen. The hydrothermal temperature of the AP influenced the distribution and yield of syngas products. The maximum hydrogen content was 57% in all experiments (syngas max output, 1657 mL). This paper provides new possibilities in the treatment of agricultural waste and the synthesis of sustainable energy.
