A method and a system for generation of high performance precipitated silica from rice husk ash |
| abstract |
The invention provides a method for obtaining precipitated silica from a rice husk ash. The method includes reacting sodium hydroxide with the rice husk ash in the ratio of about 1 :1 weight /weight to about 1 :4 weight /weight to obtain a sodium silicate solution, co-injecting a carbon dioxide gas with the sodium silicate solution for obtaining a slurry comprising of silica and sodium carbonate solution, separating the slurry to obtain precipitated silica with high surface area and regenerating the sodium hydroxide from the sodium carbonate solution. A system for obtaining precipitated silica from a rice husk ash is also provided. |
