A Novel Process And Apparatus For The Manufacture Of Precipitated Silica From Rice Husk Ash

Abstract: A novel process for the manufacture of precipitated silica from rice husk ash, having a surface area ranging from 50-400m2/g and tap density of 80-600kg/m3 having multiple applications in the field of rubbers and plastics, paints, toothpastes, catalyst, carrier agent, insulation, stabilizing and desiccants. The process method for silica precipitation is novel, wherein the chemicals used are regenerated making it a closed loop operation. The extraction process through digestion, precipitation and regeneration are done based on the application specifies, so as to get the required particle size and densities.
