Calcination Method

High surface area calcium aluminate is synthetized within a short time by using a carbon template solid state calcination method which involved addition of carbon black into the CaCO3 and Al2O3 powders, calcination, and carbon removal by steam. Vary carbon black dosage changed the textural properties of the calcium aluminate, such as the surface area. By varying carbon black dosage from 0 to 10.0 wt%, the calcium aluminate with a surface area ranging from 21.5 to 41.2 m2and#183;g–1 are successfully synthesized within 14.0 h. Furthermore, the nanometer sized CaCO3 and Al2O3 powders comprising carbon black could markedly reduce the calcination temperature without reducing the surface area. This research might lead to the cost-effective synthesis of calcium aluminate (Ca12Al14O33) in a short synthesis period.

Abstract Mesoporous materials are promising structures for application in catalysis and adsorption due to high surface area and large pore size. Mesoporous materials were synthesized by the hydrothermal method with novel surfactants, distinct from those observed in the literature, in order to carry out a study of its structure and to obtain materials with better textural properties. The structures synthesized with the surfactants Igepal CO630 and Brij O20 presented the best results of specific surface area, 1074 and 1075 m2.g-1, respectively. The obtained materials were characterized by XRD, TG/DTG, N2 adsorption-desorption, and FTIR techniques. XRD patterns indicated that the highly ordered mesoporous silica structures, such as MCM-41 and MCM-48, using CTMABr as the structure-directing agent and the SBA-15, SBA-16 and other SBA structures using different block copolymers were obtained. Through N2 adsorption-desorption isotherms, it was observed type IV isotherms, attributed to mesoporous materials. The FTIR spectra presented similar behaviors with characteristic vibrational bands of MCM and SBA type materials.

The effects of carbon black specific surface area and morphology were investigated by characterizing four different carbon black additives and then evaluating the effect of adding them to the negative electrode of valve-regulated lead–acid batteries for electric bikes. Low-temperature performance, larger current discharge performance, charge acceptance, cycle life and water loss of the batteries with carbon black were studied. The results show that the addition of high-performance carbon black to the negative plate of lead–acid batteries has an important effect on the cycle performance at 100% depth-of-discharge conditions and the cycle life is 86.9% longer than that of the control batteries. The excellent performance of the batteries can be attributed to the high surface area carbon black effectively inhibiting the sulfation of the negative plate surface and improving the charge acceptance of the batteries.
