Abstract

The desulfurization ash contains high content of CaSO3, which makes it difficult for its resource utilization. In the present study, the physical–chemical performance of the sintering flue gas desulfurization ash from a typical steel corporation was analyzed. On this basis, the H2O2 oxidation modification, MnSO4 catalytic modification and air oxidation test with different process conditions of it were studied, and the best process conditions of desulfurization ash modification were analyzed. Considering the test results and the industrial practice, the optimal process conditions were thought as: hydrogen peroxide was oxidant, pH value was 5.5, the molar ratio of H2O2 and CaSO3 was 1:1, the slurry solid content was 10%, and the reaction time was 1.5 h, and under these conditions, the CaSO3 conversion rate reached 98%. However, MnSO4 was not suggested to be added for oxidation of sintering semi-dry desulphurization ash.
