Zusammenfassung: | A hydrogenation catalyst and a preparation method therefor and a use thereof. The catalyst comprises a carrier and hydrogenation active metal components loaded on the carrier. The hydrogenation active metal components contain at least one VIB group metal component and at least one VIII group metal component, and the carrier consists of phosphorus-containing alumina. When the hydrogenation catalyst is measured by a hydrogen-temperature programmed reduction (H2-TPR) method, the ratio S=P low-temperature peak/P high-temperature peak of the peak height P low-temperature peak of a low-temperature reduction peak located at 300-500 DEG C to the peak height P high-temperature peak of a high-temperature reduction peak located at 650-850 DEG C is between 0.5-2.0, preferably 0.7-1.9, and further preferably 0.8-1.8. When being used for hydrotreatment, the hydrogenation catalyst has an excellent heteroatom removal effect and excellent stability. |
