摘要: 通过在氧化铝载体加入微米级植物固体纤维丝扩孔,制备出NiMo柴油加氢脱硫催化剂。采用BET、XRD、SEM、Raman与TEM对制备的载体及催化剂进行表征研究。结果表明,植物固体纤维丝能够在催化剂中构建出部分直筒大孔,NiMo活性组分在催化剂载体上实现了高度分散,活性相MoS2堆叠层数集中在3-5层,平均MoS2条长度为4.49 nm。研究了催化剂载体中植物固体纤维丝含量对催化剂活性的影响,并与常规氧化铝载体催化剂进行了对比,高压微反评价结果表明,开发的含有3%(质量分数)植物固体纤维丝NiMo柴油加氢脱硫催化剂比常规NiMo催化剂活性更高,其加氢脱硫活性提高了5%-15%。Abstract: The micron-sized plant fiber filaments were used as templates to obtain cylindrical macropores during the gamma alumina support preparation. The support was then used to prepare the NiMo/alunima diesel hydrodesulfurization catalyst. The prepared catalyst and alumina support were characterized by BET, XRD, SEM, Ruman and TEM. The characterization results showed that the plant fiber filaments in the catalyst constructed some straight holes, the NiMo active components on the catalyst support were highly dispersed and the active phase MoS2 stacked layers were mainly concentrated in 3-5 layers and the average length of MoS2 bars was 4.49 nm. The influence of plant fiber filament content on the performance of diesel hydrodesulfurization catalyst was studied and compared with conventional catalysts. The high-pressure micro-reverse evaluation results show that the developed NiMo diesel hydrotreating catalyst containing 3% (mass ratio) plant fiber filament has 5%-15% higher activity than the conventional NiMo catalyst.
