Raw duck eggshells were calcined at temperatures between 300 to 900 °C, for 1, 3, and 5 h. Both the raw and calcined duck eggshells were characterized by FTIR, STA, XRD, XRF, TEM, BET, a particle size analyzer, and an impedance analyzer. The proper calcination conditions are: 900 °C and 1 h, yielding calcium oxide with a purity of 99.06 % w/w.

Calcium looping (i.e., CO 2 capture by CaO) is a promising second-generation CO 2 capture technology. CaO, derived from naturally occurring limestone, offers an inexpensive solution, but due to the harsh operating conditions of the process, limestone-derived sorbents undergo a rapid capacity decay induced by the sintering of CaCO 3 .

the conditions tested. Calcined materials showed a general decrease in re-activity with sulfur doxide as the temperature was raised. When simul-taneously calcined and sulfated, both materials reacted better at the higher temperatures because of the increased degree of calcination during the short 15-min retention time.

This process is called sorption-enhanced hydrogen production (SEHP). H 2 can be concentrated up to 99.9% using a pressure swing adsorption system (PSA). By varying the pressure, the PSA allows the separation of a gas mixture based on the different affinities for each gaseous species to be adsorbed on a liquid or solid.

For example, calcium carbonate is one of the most common forms of oral calcium supplements. Calcium carbonate contains 40% elemental calcium, with the remaining 60% being carbonate. Calcium lactate is technically just 13% elemental calcium. Check the label to find out how much elemental calcium is provided per pill.

Natural raw materials include minor quantities of various elements such as P, Ti, Cr and Mn. Waste materials such as lime, fly ash and slags containing calcined calcium (CaO as opposed to CaCO 3 ) are particularly attractive in avoiding the heat required for dissociating carbonate (Sec B5.5).
