Abstract:

The features and present research situation of solid desulfurizers of iron, zinc, manganese and activated carbon systems etc. are analyzed and summarized. Iron oxide belongs to atmospheric temperature desulfurizer and can be used independently or used together with atmospheric temperature hydroxide radical sulfur hydrolyzed catalyst, but its desulfurization accuracy is low. After compounding, its desulfurization accuracy is improved, but the temperature is raised. The desulfurizer of zinc system has a higher desulfuriza?鄄tion temperature, but its desulfurization accuracy is reliable, it is widely used in industry. The desulfurizer of manganese system has a superior performance under high temperature and a strong regeneration capability, but it has a small sulfur capacity at lower temperature and it is normally used for smoke desulfurization under high temperature. The desulfurizer of activated carbon system is more suitable for the removal of organic sulfur.
