摘　　要：The purpose of this work is to convert organic wastewater into oxidants(H2O and CO2)to promote biomass gasification during the chemical looping process to achieve high-H2/CO-ratio syngas.A tert-butanol solution was selected as the model organic wastewater to generate enough H2O and CO2 to promote corn stalk chemical looping gasification(CLG).A series of CLG experiments was conducted at 850℃ under various degrees of oxygen excess(Ω).AnΩof approximately 0.9 led to the highest hydrogen yield and fixed carbon conversion compared with the other cases.Chemometrics and thermodynamic analysis further validated the possibility of corn stalk CLG using a tert-butanol solution.The results show that CLG of biomass-organic wastewater can both treat organic waste and promote chemical looping processes.
