abstract
The objective of the research is to use Na2CO3/FeOOH, a regenerable nanoporous solid sorbent, for reducing the energy required to separate and capture at least 95% of post-combustion Carbon Dioxide (CO2) from power plants to less than 1,000 kJ/kg of captured CO2 at a cost below $10/ton. The research focused on developing an environmentally friendly, widely available inorganic compound-based solid sorbent for low-energy consumption CO2 separation. Na2CO3 was used since it is cheaper than K2CO3 and more readily available. This is relevant because many technologies have already been developed for the capture of CO2. In recent years, increasing interest has been shown in using supported solid sorbents to improve the rate of CO2 capture while reducing the amount of energy required by the process. The use of a nanoporous supporting material increases the sorption capacity of the solid sorbent. The well-known wet impregnation method was used to prepare the solid sorbent. The catalytic function of the support material (FeOOH) also improves desorption kinetics. These characteristics could reduce the amount of energy required for separation to occur. It was found that Na2CO3/FeOOH appears a promising alternative to K2CO3. note
