在超声波作用下,采用单分子层剥离-重堆技术,正丁基锂柱插MoS2夹层,合成了前驱体LixMoS2和磷(P)改性Ni/MoS2复合材料,以二苯并噻吩、喹啉催化加氢为探针反应,考察了其催化活性。实验结果表明,P改性Ni/MoS2催化剂具有很强的加氢脱硫、脱氮活性和选择性,P元素的最佳添加量为2.05%,二苯并噻吩、喹啉的转化率分别达到了98.2%、99.8%。XRD、FT-IRI、CP-EDS、BET的分析检测,揭示了P改性Ni/MoS2催化剂的微观结构和内在规律性。
By effect of ultrasonic waves, premonitory LixMoS2 and phosphorus modified Ni/MoS2 composite were prepared by n-butyl lithium intercalating in the MoSe layers, using the single-molecula layer exfoliated-restacked technology. The effect of catalyst on the performance was investigated with dibenzothiophene and quinoline hydroprocessing over phosphorus modified Ni/MoSw as probe reaction. The results showed that phosphorus modified Ni/MoS2 had high activity and selectivity in hydrodesulfurization (HDS), hydrodenitrogenation (HDN). The optimum phosphorus content was 2. 05%. Conversion of dibenzothiophene and quinoline reached 98.2%, 99.8% respectively. Micro-structure and essence disciplinarian of phosphorus modified Ni/MoS2 were disclosed by XRD, FT-IR. ICP-EDS. BET detection. It could provide experimental data in synthesizing new hydrogenation catalysts for ultra-low sulfur and nitrogen productions.
