Modified cenospheres are interesting supports for the CO 2 methanation catalyst. Their perforation led to better development of specific surface area and basicity. The presence of Mg–Al oxides in the coating improved the dispersion of nickel. Mg–Al oxides are a source of surface basic centers.
Cenospheres (CS), similar to fly ash, are mainly aluminosilicate spheres filled with gases from the coal combustion process: carbon dioxide and nitrogen with a Si/Al ratio from 1.5 to 3.5 . Cenospheres in the presence of a large amount of mullite [ 8, 9 ] show low thermal expansion, considerable thermal stability, and high creep and crack ...
The colour of cenospheres varies from gray to almost white and their density is about 0.4–0.8 g/cm3 (0.014–0.029 lb/cu in), which gives them a great buoyancy. Cf. glass microspheres. Cenospheres are hard and rigid, light, waterproof, innoxious, and insulative. This makes them highly useful in a variety of products, notably fillers.
Cenospheres What are Cenospheres also called Microspheres? fuel fly ash from a coal power plant 97-98 % of fly ash is waste/slag 2-3% of fly ash are round and hollow: Cenospheres Fly ash quality is direct linked to the coal used. Lower coal quality leads to lower fly ash consequently lower Cenospheres quality. .

A cenosphere is a lightweight, inert, hollow sphere made largely of silica and alumina and filled with air or inert gas, typically produced as a coal combustion byproduct at thermal power plants. The color of cenospheres varies from gray to almost white and their density is about 0.4–0.8 g/cm3, which gives them a great buoyancy. Cenospheres are hard and …
This work reports on the separation of cenospheres from lignite fly ash through a wet separation process-the sink-float method. A better quality of cenospheres could be achieved through a physical–chemical approach using an acetone–water mixture as a medium. This work aimed to elucidate the correlation between the structure, …
The incorporation of cenospheres in concrete reduces the density of the concrete due to its shape and structure.
