A series of ZSM-5/FDU-12 (ZF-x) composite material with MFI microporous structure and face-centered cubic structure were successfully synthesized using the nano-assembly method under different water bath temperatures. The bath temperature had an apparent influence on the material’s physical texture property. The catalytic hydrotreating performance were evaluated inside fix-bed unit, under the reaction conditions of 5 MPa and 350 °C. The sulfur and nitrogen contents of the products obtained from NiMo/ZFA-30 catalyst were reached 11.5 ppm and 4.8 ppm, respectively. The moderate acidity and the highest sulfidation ratio of active phases were responsible for the highest hydrodesulfurization (98.9 %) and hydrodenitrogenation (99.3 %) efficiency over the NiMo/ZFA-30 catalyst.

分级ZSM-5/FDU-12复合材料理化性质及其催化柴油加氢脱硫性能的调整

采用纳米组装法在不同水浴温度下成功合成了一系列具有MFI微孔结构和面心立方结构的ZSM-5/FDU-12(ZF-x)复合材料。浴温对材料的物理织构性能有明显的影响。在固定床装置内,在5 MPa和350 ℃的反应条件下评估催化加氢处理性能。NiMo/ZFA-30 催化剂产物的硫和氮含量分别达到 11.5 ppm 和 4.8 ppm。与 NiMo/ZFA-30 催化剂相比,中等酸度和活性相的最高硫化率是最高的加氢脱硫 (98.9%) 和加氢脱氮 (99.3%) 效率的原因。
