Porous spherical calcium aluminate-supported CaO-based

May 29, 2019· The biomass-templated calcium aluminate-supported CaO pellets performed much better in cyclic CO 2 capture than the original CaO pellets, which could be attributed to two reasons as schemed in Fig. 9. On one hand, the incorporation of calcium aluminate-based supports enhanced the anti-sintering ability compared to the original sorbent.

Calcium | Article about calcium by The Free Dictionary

Calcium is produced industrially by two methods: (1) by heating a briquetted mixture of CaO and powdered aluminum at 1200°C in a vacuum of 0.01-0.02 mm Hg; the calcium vapors, evolved according to the equation 6CaO + 2A1 = 3CaO ⋅ A1 2 O 3 + 3Ca, condense on a cold surface; (2) by electrolyzing a melt of CaCl 2 and KCl, using a liquid copper

Caco3 | Article about Caco3 by The Free Dictionary

Calcium carbonate occurs in nature in two mineral forms with differing crystalline structures: aragonite and the widely distributed calcite. Calcium carbonate decomposes when heated above 900°C: CaCO 3 = CaO + CO 2 (a means of obtaining lime). It is sparingly soluble in water (14 mg calcite per liter at 18°C) and readily soluble in acids.

Imerys Aluminates - About Aluminates

Calcium aluminates or hydraulic cements "Calcium aluminates, "alumina cements" or "high alumina cements" are obtained by the reaction at high temperature of lime (from limestone) and alumina (contained in natural minerals like bauxite). The product obtained after cooling is a hard mineral: calcium aluminate clinker.
