以高岭土和水玻璃为原料,采用水热法原位晶化合成了NaY分子筛复合材料,通过离子交换法改性并制备出催化裂化催化剂,利用X射线荧光仪、N2吸附-脱附仪、扫描电子显微镜等仪器对试样进行结构表征,在固定流化床微型反应器装置上进行催化剂裂化反应性能评价。结果表明:该NaY分子筛复合材料的外比表面积为93.70 m2/g,介孔孔容为0.19 cm3/g,颗粒直径约在300~500 nm;改性后复合材料的介孔主要分布在2~20 nm,且为双孔分布,分布峰分别为3.8,5.6 nm;与常规NaY型分子筛催化剂相比,采用该NaY型分子筛复合材料所制备的催化剂其反应转化率、液化气和总液体收率依次提高6.18,5.16,1.61个百分点,重油收率下降3.34个百分点,生焦因子下降0.80。
- Abstract:
-
NaY molecular sieve composite material was in-situ synthesized by kaolin and water glass using hydrothermal method, the fluid catalytic cracking catalyst was prepared by NaY molecular sieve composite material modified through ion exchange method. The structure of the samples was characterized by X-ray fluorescence, N2 adsorption desorption, scanning electron microscopy, and other instruments. The catalytic cracking reaction performance was evaluated on a fixed fluidized bed micro reactor device. The results indicated that the external specific surface area of the NaY molecular sieve composite material was 93.70 m2/g, the mesoporous pore volume was 0.19 cm3/g, and the particle diameter was about 300-500 nm. The mesopores of the modified composite material were mainly distributed in the range of 2-20 nm and exhibited a bimodal pore distribution, with distribution peaks of 3.8 and 5.6 nm respectively. Compared with conventional NaY-type molecular sieve catalysts, the conversion rate, liquefied gas and total liquid yield of catalyst prepared by this NaY-type molecular sieve composite material increased by 6.18, 5.16, and 1.61 percentage points respectively, while the heavy oil yield decreased by 3.34 percentage points and the coking factor decreased by 0.80.
