Abstract
Process for obtaining low carbon white ash from rice husks for the manufacture of refractory construction materials, in which the rice husks are heated to a temperature below the crystallization temperature of the SiO2 of the husks of rice, for the separation of the volatile components and for the transformation of the fixed carbon into a gaseous compound, and in which the ash of the rice husks thus obtained is subsequently malleabilized at a temperature higher than the SiO2 crystallization temperature, to obtain a uniform crystallization structure of SiO2, characterized in that, in the first place, the rice husks are heated without air intake to a relatively low first separation temperature, in the range of 200 to 450ºC, exclusively for the separation of the recombinant volatile components.
