Highly dispersed palladium/carbon nanometer tube catalyst for anthraquinone hydrogenation and preparation method thereof

The invention discloses a highly dispersed palladium/carbon nanometer tube catalyst for anthraquinone hydrogenation and a preparation method thereof, and relates to a catalyst and a preparation method. According to the invention, a carbon nanometer tube industrial product with good conductivity, heat conductivity, high mechanical strength and huge external specific surface is used as a palladium carrier; simultaneously ultrasonic is utilized to further enhance the dispersity and uniformity of palladium and the carbon nanometer tube; and a nanometer palladium catalyst uniformly loaded on the surface of the carbon nanometer tube is prepared in a slurry reactor by adopting a liquid phase reduction method. The catalyst needs no extrusion molding and can be directly suspended in the liquid phase for normal-pressure or pressurized hydrogenation of anthraquinone; the activity of the catalyst is not reduced after the catalyst is used for a plurality of times by filtration and separation; moisture, acid and alkaline d
