“…The actual amount of oxygen transferred by the oxygen carrier material during operation is called the oxygen transfer capacity (OTC). Figure 10 displays the maximum theoretical oxygen transfer capacities of certain oxygen carrier materials, as calculated by Equation (16). In short, the oxygen transfer capacity, denoted by OTC, is the amount of oxygen (in wt%), which the oxygen carrier can deliver to the fuel per cycle [143].…”

“…Therefore, alternative processes have been developed in which these CO 2 emissions can be avoided. Among current and emerging technologies for CO 2 capture, chemical looping combustion (CLC) was frequently mentioned as a particularly promising approach to combining CO 2 capture and energy production [10,15,16]. This technology can also be included in the oxyfuel combustion branch of CCS, as in this process also, all diluting components of the air are separated before the combustion of the fuel.…”

This review aims to give more understanding of the selection and development of oxygen carrier materials for chemical looping. Chemical looping, a rising star in chemical technologies, is capable of low CO2 emissions with applications in the production of energy and chemicals. A key issue in the further development of chemical looping processes and its introduction to the industry is the selection and further development of an appropriate oxygen carrier (OC) material. This solid oxygen carrier material supplies the stoichiometric oxygen needed for the various chemical processes. Its reactivity, cost, toxicity, thermal stability, attrition resistance, and chemical stability are critical selection criteria for developing suitable oxygen carrier materials. To develop oxygen carriers with optimal properties and long-term stability, one must consider the employed reactor configuration and the aim of the chemical looping process, as well as the thermodynamic properties of the active phases, their interaction with the used support material, long-term stability, internal ionic migration, and the advantages and limits of the employed synthesis methods. This review, therefore, aims to give more understanding into all aforementioned aspects to facilitate further research and development of chemical looping technology.

The CO 2 emitted by iron and steel industry accounts for 6% of the global anthropogenic CO 2 emission. As the control of CO 2 emission becomes increasingly stringent all over the world, the iron and steel industry now is facing an unprecedented crisis. And now even the most advanced technologies for reducing carbon emission have reached the bottleneck, so many countries in the world are striving to develop the breakthrough technologies for significantly reducing the carbon emission. The current progress and future research of steelmaking program with ultra-low CO 2 emission in Europe are stated, among which TGR-BF, HIsarna, ULCORED, ULCOWIN and ULCOLYSIS are considered to be the most promising technologies. Combined with the technology of carbon capture and storage, CO 2 emission can be reduced by as much as 80%. Compared with the traditional technologies, investment cost and operating cost are much lower.

“…Chemical looping combustion (CLC) is an emerging approach for CO 2 capture where metal oxides are used as the oxygen source in place of air to combust the fuel [1][2][3][4][5][6]. This can potentially result in considerable energy savings compared to the more established technologies of post-combustion, pre-combustion and oxy-combustion [7][8][9][10][11][12].…”

Chemical looping combustion (CLC) of n-hexadecane and n-heptane with copper and manganese oxides (CuO and Mn 2 O 3 ) has been investigated in a fixed bed reactor to reveal the extent to which low temperature CLC can potentially be applicable to hydrocarbons. The effects of fuel to oxygen carrier ratio, fuel feed flow rate, and fuel residence time on the extent of combustion are reported.Methane did not combust, while near complete conversion was achieved for both n-hexadecane and n-heptane with excess oxygen carrier for CuO. For Mn 2 O 3 , complete reduction to Mn 3 O 4 occurred, but the extent of combustion was controlled by the much slower reduction to MnO. Although the extent of cracking is relatively small in the absence of cracking catalysts, for the mechanism to be selective for higher hydrocarbons suggests that the reaction with oxygen involves radicals or carbocations arising from bond scission. Sintering of pure CuO occurred after repeated cycles, but this can easily be avoided using a support, such as alumina. The fact that higher hydrocarbons can be combusted selectively at 500 °C and below, offers the possibility of using CLC to remove these hydrocarbons and potentially other organics from hot gas streams.
