Since the time of the industrial revolution, the atmospheric CO(2) concentration has risen by nearly 35 % to its current level of 383 ppm. The increased carbon dioxide concentration in the atmosphere has been suggested to be a leading contributor to global climate change. To slow the increase, reductions in anthropogenic CO(2) emissions are necessary. Large emission point sources, such as fossil-fuel-based power generation facilities, are the first targets for these reductions. A benchmark, mature technology for the separation of dilute CO(2) from gas streams is via absorption with aqueous amines. However, the use of solid adsorbents is now being widely considered as an alternative, potentially less-energy-intensive separation technology. This Review describes the CO(2) adsorption behavior of several different classes of solid carbon dioxide adsorbents, including zeolites, activated carbons, calcium oxides, hydrotalcites, organic-inorganic hybrids, and metal-organic frameworks. These adsorbents are evaluated in terms of their equilibrium CO(2) capacities as well as other important parameters such as adsorption-desorption kinetics, operating windows, stability, and regenerability. The scope of currently available CO(2) adsorbents and their critical properties that will ultimately affect their incorporation into large-scale separation processes is presented.

Publisher Summary The hydrogenation of carbon dioxide to methane and other hydrocarbons is an interesting catalytic alternative to the Ftscher–Tropsch reaction. One of the metals known to be active for this process is cobalt. To get a better understanding of the catalytic process, it is of great interest to elucidate the microscopic processes taking place in the various catalytic steps. Included are structural and chemical changes of the catalyst surface, which most likely influence the overall catalytic performance or the activation and deactivation of the catalyst. Concerning the hydrogenation of carbon dioxide on cobalt, pioneering work by Amariglio et al . revealed interesting correlations between activation/deactivation behavior and oxidizing pretreatments of the catalysts. Intensive studies were also performed on CO hydrogenation on supported Co catalysts providing a comprehensive background for the understanding of CO 2 hydrogenation. However, resent results also showed that the catalytic behavior of supported or compact material reveals different aspects. Thus, based on the earlier work, this chapter focuses on a thorough investigation of the respective properties of the catalytic system of compact materials. To achieve extensive information, the experimental work includes a broad variety of methods performed by both groups in Erlangen and Krakow.
