Abstract
Nowadays, the emission of factory is one of the source of SO2. In the normal way to deal with SO2, we need a lot of absorbent and neutralizer. The equipment cost is very large, and this way will produce many secondary pollutants which enhance the after treatment difficulty. As the air pollution is growing, the government emission standard becomes stricter and stricter. A company will need more cost in the future which taking bad influence for expenditure. We developed the electrochemical double cell (EDC) using the electromotive force (EMF) between cathode and anode material to promote the SO2 decomposition on the catalyst surface for reducing the emission of SO2.According to the real situation, the larger area is needed. Using the anode honeycomb which has the best area volume ratio to be the substrate. It can reduce the space to reach the same result.In the EDC production process, the electrolyte layer is most important step. The effectiveness depends on the densification of the electrolyte layer. However, basing on the complicate structure of honeycomb, we try different coating method and component ratio of coating solution to reach the effect of commercial cell plate’s electrolyte layer.
