Abstract
A catalyst has a carrier and a hydrogenation active metal component supported on the carrier. The hydrogenation active metal component contains at least one Group VIB metal component and at least one Group VIII metal component, and the carrier is composed of phosphorus-containing alumina. When the hydrogenation catalyst is measured using a hydrogen temperature programmed reduction method (H-TPR), the ratio of the peak height of the low-temperature reduction peak, P, at a temperature of 300-500° C. to the peak height of the high-temperature reduction peak, P, at a temperature of 650-850° C., i.e. S=P/P, is 0.5-2.0; preferably 0.7-1.9, and more preferably 0.8-1.8. The hydrogenation catalyst shows excellent heteroatom removal effect and excellent stability when used in hydrotreatment.
