摘　　要：浆态床渣油加氢工艺是加工劣质油品的有效方法,由于原料具有高沥青质、高金属含量的特点,工艺的核心在于提供稳定高效的加氢裂化催化剂。油溶性催化剂前体能够原位转化为纳米级尺寸的催化剂活性相,其分散度高、加氢活性高,因而成为浆态床渣油加氢工艺的首选。本文主要介绍了4类常见的油溶性有机钼化合物,即二烷基(芳基)二硫代氨基甲酸钼(Mo-DTC)和二烷基二硫代磷酸钼(Mo-DTP)、环烷酸钼(MoNaph)、异辛酸钼、六羰基钼,比较它们在氢气和硫作用下的转化过程以及对重质原料的加氢性能,找出各自在应用过程中的优缺点,为深入研究和设计开发油溶性催化剂前体提供思路和借鉴。The slurry phase hydrocracking is effective to treat inferior feedstocks with high content of asphaltene and metal, and the core is the stable and efficient hydrocracking catalyst. Due to the high dispersion and activity, the oil-soluble catalyst precursor, which could be in-situ converted into nanoscale reactive phase, is the best choice for slurry-bed residue hydrogenation. Four kinds of commonly used oil-soluble organic molybdenum compounds, Mo-DTC and Mo-DTP, MoNaph,molybdenum 2-ethyl hexanoate, and Mo(CO)6, were introduced in this paper. By reviewing their conversion in the presence of H2 and sulfur-containing substance, and the hydrogenation performance in residual oil processing, we discussed the advantages and disadvantages of their applications to provide references for developing highly active oil-soluble catalyst precursors.
