英文摘要：

The research findings of CO_2 capture technology using solid potassiumbased sorbents are summarized,while factors influencing the carbonation and regeneration characteristics of pyrolysis products from KHCO_3 crystal with strong carbonation capabilities analyzed,during which optimum experimental conditions for carbonation and regeneration tests obtained.A comparison of carbonation characteristics between various potassium-based sorbents with different supports is made,among which K_2CO_3/Al_2O_3 is found to be more efficient.Study results on carbonation-regeneration cyclic reaction of K_2CO_3/Al_2O_3 sorbent show that the sorbent has excellent performance in the cyclic reaction.Suggestions for further study on this side are simultaneously put forward.
