摘要： Disclosed is a hydrogenation catalyst, its preparation and application thereof, which catalyst comprises a carrier and a hydrogenation active metal component supported on the carrier, wherein the hydrogenation active metal component comprises at least one Group VIB metal component and at least one Group VIII metal component, the carrier being composed of phosphorus-containing alumina; when the hydrogenation catalyst is measured using a hydrogen temperature programmed reduction method (H 2 -TPR), the ratio of the peak height of the low-temperature reduction peak, P low-temp peak , at a temperature of 300-500 °C to the peak height of the high-temperature reduction peak, P hi-temp peak , at a temperature of 650-850 °C, i.e. S = P low-temp peak /P hi-temp peak , 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.

摘要： The invention relates to a hydrocracking process and system. The gas oil feedstock and hydrogen are mixed and reacted in a hydrotreating unit. The resulting reaction effluent is sent to a first hydrogenation cracking unit and reacted by contacting a hydrogenation cracking catalyst I to obtain light fraction I rich in paraffins and heavy fraction I rich in cyclic hydrocarbons. The heavy fraction I is mixed with hydrogen and reacted in a second hydrogenation cracking unit, thereby producing heavy fraction II rich in cyclic hydrocarbons. The present invention wholly realizes the high-selective directional conversion of gas oil feedstock according to the chain structure and the ring structure and can produce chemical raw materials rich in paraffins and naphthenic speciality oil rich in cyclic hydrocarbons.
