Abstract
A large amount of CO
2
is emitted from power generation process of coal-fired power plants. Efficient capture and resource utilization of CO
2
from flue gas is particularly important for carbon emission reduction. CO
2
chemical absorption from post-combustion flue gas is the most mature separation method
and some CO
2
capture projects have been successfully implemented
but there are still shortcomings of high cost and high energy consumption. The development of new efficient CO
2
absorbents and process optimization have become the focus of current research. The connection of CO
2
chemical absorption and catalytic synthesis of chemicals and fuels from CO
2
hydrogenation in flue gas is an effective way to reduce carbon emission in coal-fired power plants. With the continuous deepening of CO
2
catalytic conversion research
domestic and foreign researchers have made some progress in CO
2
catalytic hydrogenation to chemicals. Firstly
the carbon capture mechanism and renewable energy consumption of monoamine absorbents were introduced
and the CO
2
absorption performance
energy consumption reduction principle and carbon capture process of new absorbents (mixed amine solution
two-phase absorbent and functionalized ionic liquid) were further reviewed. The research status of CO
2
desorption catalysts and process parameter optimization in reducing renewable energy consumption were summarized. Then
based on the diff
erent types of CO
2
hydrogenation products (methanol
low carbon olefins and high carbon hydrocarbons)
the research progress of CO
2
catalytic hydrogenation catalysts was investigated. Finally
the development direction of CO
2
capture by chemical absorption method after combustion and CO
2
hydrogenation catalysts were prospected.
