Preparation of CO2 adsorbents and techno-economic analysis for CO2 capture and utilization

However, CCU also leads to high costs from the sorbents desorption and CO2 utilization. To further improve CCU, the Integrated Carbon Capture Utilization (ICCU) process was proposed, where CO2 captured in sorbents can be directly used without desorption of sorbents and the purification of CO2. Thus, the cost can be further reduced by simplifying the procedures.

The comparison between ICCU process and CCU process has also been investigated, thus series results including CO production, CaCO3 consumption, purge production, energy efficiency, the total annual cost (TAC), and the total cost of CO are used to confirm that ICCU is a better choice for further industrial applications. Moreover, the effects of the H2 price on the total cost of CO for both CCU and ICCU processes have also been discussed because the H2 price has the dominant influence on the economic results.<br><br><i>Thesis embargoed until 31 July 2027</i>.<br>
