Summary: The effect of adding calcium to rice husk in chemical looping gasification (CLG) was studied, revealing that calcium can significantly improve the performance of the gasification process, but may cause aggregation and sintering at high concentrations. (CH3COO)2Ca was found to be more beneficial than CaCl2 in enhancing gasification efficiency, with 6% (CH3COO)2Ca leading to optimal gasification efficiency and gas yield in the CLG process.
