本発明は、モリブデンアミン錯体触媒ならびにその調製方法およびその使用を開示する。モリブデンアミン錯体触媒の調製方法は、以下の工程：分散媒、すなわち炭化水素油の存在下、六価のモリブデン化合物を、炭素原子数がＣ４またはそれ以上である少なくとも１つの脂肪族アミン化合物と反応させて活性金属触媒前駆体を得る工程；および活性金属触媒前駆体を分散媒、すなわち炭化水素油中に均一に分散させてモリブデンアミン錯体触媒を得る工程を含む。本発明のモリブデンアミン錯体触媒を石炭直接液化反応に適用すると、必要な反応圧力を大幅に低減させ、鉄系触媒と同等の油収率を達成するように、石炭の転化率ならびにアスファルテンおよびプレアスファルテンの油への転化率を大幅に向上させることができる。 The present disclosure discloses a molybdenum amine complex catalyst and a preparation method and use thereof, wherein, the method for preparing the molybdenum amine complex catalyst comprises the following steps: in the presence of a dispersion medium hydrocarbon oil, reacting a hexavalent molybdenum compound with at least one aliphatic amine compound having C4 or more carbon atoms to obtain an active metal catalyst precursor, and uniformly dispersing the active metal catalyst precursor in the dispersion medium hydrocarbon oil to obtain the molybdenum amine complex catalyst. When the molybdenum amine complex catalyst of the present disclosure is applied to the direct coal liquefaction reaction, it can significantly improve the conversion rate of coal and the conversion rate of asphaltene and preasphaltene to oil, allowing the required reaction pressure to be significantly reduced while achieving an oil yield comparable to that of the iron-based catalyst.
