| titleOfInvention | Low-temperature reduced catalytic cracking flue gas sulfur-transfer agent and preparation process thereof |
| abstract | The invention belongs to the technical field of flue gas desulfurization of the petroleum refining industry and discloses a high-efficiency catalytic cracking flue gas sulfur-transfer agent which has the good reduction ability at the low temperature and a preparation process thereof. A mechanical dispersing grinding high-specific-surface-area magnesia-alumina source and other element compounds are used, and the high-dispersion and high-sphericity-degree low-temperature reduced catalytic cracking flue gas sulfur-transfer agent is obtained through a method comprising the steps of forming, screening, roasting and hydration. According to the agent and the process, raw materials which are small in particle and large in specific surface area are preferred, and the produced catalytic cracking flue gas sulfur-transfer agent is uniform in particle and good in metal ion dispersion, so that sulfur oxides can be attached to the surface of the sulfur-transfer agent in a good mode, sulfate can be reduced at the low temperature (below 500 DEG C), the sulfur absorption of the sulfur-transfer agent is good in Sox adsorption capacity and oxidative sulfur absorption rate, the reduction performance is good, the agent and the process are applicable to catalytic cracking devices having requirements for the reduction temperature, the reduction temperature is reduced, and effects of energy conservation, emission reduction, low carbon and environmental protection are achieved. |
