中文摘要：

为寻找优质、价廉、适合合成FCC催化剂用的后备高岭土资源,以淮北煤系高岭土为原料,采用原位晶化法进行了合成NaY分子筛试验。结果表明,提纯后的淮北煤系高岭土在导向剂添加量为9%、晶化时间为24 h、晶化温度为95℃、合成体系的给料硅铝比为9.72、合成体系的碱度为2时,合成的NaY分子筛结晶度为32.9%,硅铝比为2.15,具有完好的晶型和较高的热稳定性,且孔隙发育,达到了制备炼油催化剂的要求。试验结果为以淮北煤系高岭土为原料合成FCC催化剂提供了技术依据。

英文摘要：

To find high quality, cheap and suitable for FCC catalyst synthesis of backup kaolin resource, using Huaibei coal measures kaolin as raw material, experiment was carried out via in situ crystallization method to synthesis NaY molecular sieves. Results show that after the purification of Huaibei coal measures kaolin ,with guiding agent content is 9%, crystallization time is 24 h, crystallization temperature of 95 ℃, feeding synthetic system of silicon to aluminum ratio is 9.72 synthetic system alkalinity for 2, NaY zeolite crystallinity synthesized of was 32. 9% and silica to alumina ratio of 2. 15, and synthesized products has good crystal shape, high thermal stability, and pore development, can meet the needs of preparation of oil refining catalysts. Test results provides technical basis for synthesize of FCC catalyst using huaibei coal measures kaolin as raw material.
