Abstract

The paper introduced effects of MODIFIED PYROLYSIS TAR on FLUE GAS DESULFURIZATION. This experiment selected the pyrolysis tar as the raw material, researched the effects on desulfurization performance under different modification solution, concentration, solid liquid ratio of pyrolysis tar and modified solution, calcination temperature and calcination time by 16 group orthogonal experiments. The results showed that: (1) The significance of five factors impact on the MODIFIED PYROLYSIS TAR desulfurization performance in order was: types of the modified solution>modification solution concentration>calcination time>solid-liquid ratio>calcination temperature. (2) The modified effects of nitric acid and phosphoric acid were better. (3) The higher nitrate concentration, the better modified effect of pyrolysis tar. (4) The rate of desulfurization increased mainly associated with acidic groups on the surface of the pyrolysis tar, desulfurization performance get better along with the acidic groups increasing.
