Abstract

Sulfite oxidation is critical for the stable operation of desulfurization process and the treatment & recovery of desulfurization by-products. The Fe and Co oxides modified super hydrophobic layer was prepared on tubular ceramic membranes using hydrothermal synthesis and surface modifications to realize the combination of the membrane catalysis and membrane aeration. These two oxides were approximately two-layer distributed on the membrane surface, among which the FeO located in the bottom layer and the CoO located in the upper layer. The catalytic rate of the bifunctional membrane was about 5.8 times than that of the original ceramic membrane, which was decreased with the increasing of Fe/Co ratio and declined after an initial rise with the increase of urea and cetyltrimethylammonium bromide. The conjoint effect of Fe and Co could improve the catalytic performance and reduce the dissolution loss of catalyzer. The oxidation rate tended to be constant after a 15 % decrease in 7 times experiments.

摘要

亚硫酸盐氧化对于脱硫过程的稳定运行以及脱硫副产物的处理与回收至关重要。采用水热合成法和表面改性方法，在管式陶瓷膜上制备了铁和钴氧化物改性的超疏水层，以实现膜催化与膜曝气的结合。这两种氧化物在膜表面呈近似两层分布，其中FeO位于底层，CoO位于上层。双功能膜的催化速率约为原始陶瓷膜的5.8倍，其随Fe/Co比的增加而降低，并且在随着尿素和十六烷基三甲基溴化铵增加而先上升后下降。铁和钴的协同作用可提高催化性能并减少催化剂的溶解损失。在7次实验中氧化速率下降15%后趋于恒定。
