CaO is widely used for capturing CO2 in large scale application however the work on the manufacture of CaO based pellets for the application of CO2 capture is relatively limited. In this research investigated the effect of calcium precursors (Ca(OH)2, Ca(NO3)2 and Ca(CH3COO)2) and their synthesis method (sol-mixing and wet-mixing) on pelletization. Adsorbent synthesized from Ca(CH3COO)2 as a precursor using sol-mixing pelletize to porous spherical provide the best mechanical strength and CO2 adsorption capacity 0.51 and 0.41 g CO2/ g CaO at first cycle and tenth cycle respectively. The outstanding cyclic performance of Ca(CH3COO)2 sol-mixing can be ascribed to the presence of inert support material i.e. Ca9Al6O18 and Ca12Al14O33 with suitable pore volume to prevent sintering of CaO and structure collapsing at high temperature.
