Ash to employed within the ratios 1:20 (blue ations BR 1:20 was discarded because the evaluation circles) and not (green squares). The fourth run runof BR 1:20 was discarded because the evaluation benefits had been not plausible.The results with the flow experiments might be Aluminum Hydroxide Purity & Documentation noticed in Figure three. The Flow Reactor typical CE differed from 14.88 for mixing ratio 1:20 to 17.45 for the mixing ratio 1:15. The maximum CE could be noticed for test run 2 (FR 1:10), 27.86 ; along with the lowest CE for run four (FR 1:10), ten.46 . For the ash to water mixing ratio FR 1:10, the highest variability was observed. Commonly speaking, Figure 3 shows an general typical CE of roughly 15 . It could be seen that a reduced level of ash did not lead to a remarkably decrease CE. The CE did not rise drastically with extra ash utilized within the experiment.Flow ReactorFigure three.

Cd and Pb were beneath the detection levels in all samples. 3.three. pH-Value Table four shows the pH values inside the reactor for the several test runs. All BR runs showed only smaller declines in pH worth. This can be explained by the modest amount of CO2 utilised within the BR experiment. The ash nonetheless contained non-carbonated hydroxides.

FR runs used much more CO2 then essential to assure the highest probable CE was reached.Table 1.
