This paper provides an overview of state-of-the-art carbon fixation and utilization technologies. Several carbon capture processes, such as chemical absorption and chemical looping, are reviewed and illustrated. In addition, various types of chemicals and fuels that can be produced using concentrated CO 2 (or other forms) through physical, chemical, or enhanced biological methods are presented. Among those carbon conversion methods, two promising approaches, i.e., microalgae ponds and accelerated carbonation using alkaline solid wastes, are reviewed in detail. Microalgae are fast-growing and ubiquitous photosynthetic organisms, which are rich in protein and can be converted to biodiesel fuel. They have been recognized as an alternative feedstock not only because they use CO 2 from the atmosphere but also due to their high lipid content per biomass compared to other plants. In this study, for the microalgae technologies, the principles and applications of open pond systems are discussed in terms of both technological and economic considerations. The important operation parameters affecting productivity of microalgae, including light intensity, temperature, mixing, CO 2 delivery, accumulation of dissolved oxygen, and salinity are summarized. On the other hand, accelerated carbonation technologies are an attractive and feasible approach to integrating alkaline solid waste treatment with CO 2 fixation and utilization. In this study, the performance of various carbonation processes is critically reviewed from the perspectives of process design, energy consumption, and environmental benefits. The carbonated solid product can also be used as supplementary cementitious materials in a blended cement or concrete block. Accordingly, the performance of cement pastes with carbonated product, in terms of workability and strength development, are evaluated from the cement chemistry point of view. Cement manufacturing is an energy and material intensive process, with high annual production. It is noted that, through the accelerated carbonation process, significant indirect environmental benefits can be realized.

Carbon dioxide (CO 2 ) emission reduction in industry should be a portfolio option; for example, the carbon capture and utilization by mineralization (CCUM) process is a feasible and proven technology where both CO 2 capture and alkaline waste treatment occur simultaneously through an integrated approach. In this study, the challengeable barriers and significant breakthroughs of CCUM via ex-situ carbonation were reviewed from both theoretical and practical perspectives. Recent progress on the performance of various carbonation processes for different types of alkaline solid wastes was also evaluated based on CO 2 capture capacity and carbonation efficiency. Moreover, several process intensification concepts such as reactor integration and co-utilization with wastewater or brine solution were reviewed and summarized. In addition, the utilization of carbonated products from CCUM as green materials including cement, aggregate and precipitate calcium carbonate were investigated. Furthermore, the current status of worldwide CCUM demonstration projects within the ironand steelmaking industries was illustrated. The energy consumption and cost analyses of CCUM were also evaluated.

“…Calcium and magnesium silicates present in flyash decompose into alkaline carbonates while sintering the carbonated adsorbent of sample A2 and A4. Emitted CO 2 from CaCO 3 decomposition would accelerates the decomposition of Ca and Mg silicates into carbonates and then to alkaline oxides and silicon dioxides [9]- [11]. …”

Abstract-CO 2 influe gas from anthropogenic emission is one of the major contributors for global warming among greenhouse gases (GHG). Alkaline metal oxide (CaO, MgO, etc) adsorbents got industrial importance due to its use at high temperature CO 2 capture in coal gasification to separate hydrogen gas. In this paper, we discussed on the synthesis methods of mechanical mixing, freeze granulation and dispersion methods of adsorbents for CO 2 capture. Operational issues of packed bed reactor used for CC using the alkaline earth metals doped flyash. Pore size and surface areas dependence of monolithic pellets on carbonation -calcination temperatures. CC variation with monolithic pellet size and carbonation temperatures. Breakthrough curves of adsorption for the adsorbents were discussed. Adsorbents of limestone doped with flyash were analyzed using various analytical tools and the findings were reported.Index Terms-Alkaline metal oxides doped with flyash, carbon capture, operational experiences in packed bed reactor, synthesis protocol of monolithic adsorbents.
