چکیده انگلیسی
A new concept for syngas production is proposed in which a liquid metal oxide (here copper oxide) is implemented as an oxygen carrier for chemical looping gasification. The proposed system consists of two interconnected bubble reactors as the fuel and air reactors, through which a liquid metal oxide is circulated to be successively reduced and oxidised providing the required heat and oxygen for the gasification reaction. The proposed system offers a potential process to avoid challenges such as agglomeration and sintering that are typically associated with the solid metal oxides that have previously been proposed for chemical looping gasification. Thermochemical equilibrium models are presented that show acceptable agreement with the available data. The model is then used to estimate that the carbon conversion of feedstock is up to 84.6% for gasification and 100% for combustion with the proposed concept. In addition, the mole fraction of gaseous copper oxide in the outlet stream from the air reactor is estimated to be 10â11, which implies that no further process is required to separate the evaporated copper oxide from the syngas.
