Nanostructured calcium oxides supported onto biochar obtained by pyrolysis of avocado seeds were prepared, characterized and successfully used as catalysts to produce biodiesel from waste oils. The effect of increasing calcium load (5, 10 and 20 wt%) was investigated.
Characterization of calcium oxide derived from …
The carbonation–calcination looping cycle of calcium-based sorbents is considered as an attractive method for CO 2 capture from combustion gases because it can reduce the cost during the capture steps compared to conventional technologies, e.g., solvent scrubbing. In this study, waste eggshell was used as raw material for calcium oxide-based sorbent production.

OpenAIRE | Characterization and Utilization of Calcium Oxide. Thermal decomposition of fish bones to obtain calcium oxide (CaO) was conducted at various temperatures of 400, 500, 800, 900, 1000, and 1100 °C. The calcium oxide was then characterized using X-ray diffractometer, FTIR spectrophotometer, and SEM analysis.

Calcium Titanate from stone Waste: Combustion …
Calcium titanate (CaTiO 3 ) was combustion synthesized from a calcium source of waste duck eggshell, anatase titanium dioxide (A-TiO 2 ), and magnesium (Mg). The eggshell and A-TiO 2 were milled for 30 min in either a high-energy planetary mill or a conventional ball mill. These powders were then separately mixed with Mg in a ball mill.

Calcium oxide - Wikipedia
Calcium oxide (CaO), commonly known as quicklime or burnt lime, is a widely used stone compound.It is a white, caustic, alkaline, crystalline solid at room temperature. The broadly used term "lime" connotes calcium-containing inorganic materials, in which carbonates, oxides and hydroxides of calcium, silicon, magnesium, aluminium, and iron predominate.
