The silica present in the ash combines with the sodium present in the NaOH solution and forms sodium silicate (Na 2 SiO 3) solution. At room temperature, the pH of sodium silicate (Na 2 SiO 3) filtrate was adjusted to pH 7.4 using 20% H 2 SO 4. The reaction of sodium silicate with sulphuric acid forms a white silica precipitate solution.

For the A-RHA and Cr-RHA, the amount silica was captured to be 94%. For the C-RHA, the amount of silica was 55% but the total mass recorded after the test was only 60% while this situation did not happen with the other two types (Figure 14). Because the machine cannot capture the carbon, this loss was assumed to be the amount of the carbon.
