R-Aminomethylphosphonic acid (R = diethyl and bis(2-ethylhexyl), denoted as DEAPA and 2EAPA, respectively) was applied as ligands to synthesize a series of aminomethylphosphonic molybdenum precursors (DEAPA-Mo, 2EAPA-Mo, and 2EAPA-2Mo) under moderate conditions. Single-crystal X-ray diffraction, X-ray photoelectron spectroscopy, infrared and Raman spectroscopy, scanning electron microscopy, and high-resolution transmission electron microscopy techniques were employed to analyze the samples before and after sulfidation. The samples were applied as catalyst precursors for slurry-phase hydrocracking of Karamay atmospheric residue. The effects of organic ligand chain length and Mo/P molar ratio on catalytic performance were investigated. The results indicate that 2EAPA-Mo exhibits 1.61 wt % coke formation and 85.5 wt % liquid yields. As a catalyst precursor, 2EAPA-Mo disperses well in the feed oil and upon in situ sulfidation facilitates the formation of a MoS2 phase that is highly active. The superior performance is attributed to the small particle size, short slab length, and low layer stacking number of MoS2 and the introduction of phosphorus.

浆料相加氢裂化氨基甲基膦钼催化剂的合成，表征及催化性能
R-氨基甲基膦酸（R =二乙基和双（2-乙基己基），分别表示为DEAPA和2EAPA）用作配体，以合成一系列氨基甲基膦钼前体（DEAPA-Mo，2EAPA-Mo和2EAPA-2Mo）在中等条件下。采用单晶X射线衍射，X射线光电子能谱，红外和拉曼光谱，扫描电子显微镜和高分辨率透射电子显微镜技术对硫化前后的样品进行分析。样品用作克拉玛依常压渣油的淤浆相加氢裂化的催化剂前体。研究了有机配体链长和Mo / P摩尔比对催化性能的影响。结果表明，2EAPA-Mo表现出1.61 wt％的焦炭形成和85.5 wt％的液体收率。高度活跃的2相。优异的性能归因于MoS 2的粒径小，板坯长度短，层堆叠数低以及磷的引入。
