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).An Ω of 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.
