Efficient MgO-doped CaO sorbent pellets for high temperature CO

Zhihong Xu, Tao Jiang, Hao Zhang, Yujun Zhao, Xinbin Ma, Shengping Wang

Frontiers of Chemical Science and Engineering 2021, Volume 15, Issue 3,   Pages 698-708 doi: 10.1007/s11705-020-1981-2

Abstract: Novel MgO-doped CaO sorbent pellets were prepared by gel-casting and wet impregnation. The effect of Na and MgO on the structure and CO adsorption performance of CaO sorbent pellets was elucidated. MgO-doped CaO sorbent pellets with the diameter range of 0.5 1.5 mm exhibited an excellent capacity for CO adsorption and adsorption rate due to the homogeneous dispersion of MgO in the sorbent pellets and its effects on the physical structure of sorbents. The results show that MgO can effectively inhibit the sintering of CaO and retain the adsorption capacity of sorbents during multiple adsorption-desorption cycles. The presence of mesopores and macropores resulted in appreciable change of volume from CaO (16.7 cm ∙mol ) to CaCO (36.9 cm ∙mol ) over repeated operation cycles. Ca2Mg1 sorbent pellets exhibited favorable CO capture capacity (9.49 mmol∙g ), average adsorption rate (0.32 mmol∙g ∙min ) and conversion rate of CaO (74.83%) after 30 cycles.
