英文摘要：

The latest research findings on CO2 capture technology using dry alkali-based sorbents were reviewed. Fundamental and technical characteristic were expounded. The latest scientific research productions of this process were introduced from research object, methodology and conclusion. Problems and shortage of these productions were analyzed. Based on primary experimental results, further research direction was presented from selectron of sorbent and carrier material, influence factor and experimental methodology. CO2 capture technology using dry alkali-based sorbents is low cost, less requirement of reaction condition, low energy consumption and due to its economic superiority compared with some other CO2 emission reduction technologies, it is one of the most important technologies for CO2 emission reduction.
