摘要： Described are a process and a system for hydrotreating a deoiled asphalt. The process includes: (2) introducing a deoiled asphalt and an aromatics-containing stream into a first reaction unit for hydrogenation reaction, wherein the first reaction unit comprises a mineral-rich precursor material and/or a hydrogenation catalyst, and the first reaction unit is a fixed bed hydrogenation unit; (21) fractionating the liquid-phase product from the first reaction unit to provide a first light component and a first heavy component; (31) introducing the first light component into a second reaction unit for reaction, to provide a gasoline component, a diesel component and/or a BTX feedstock component; and (32) introducing the first heavy component to a delayed coking unit for reaction; or using the first heavy component as a low sulfur ship fuel oil component.

摘要： 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 (H2-TPR), the ratio of the peak height of the low-temperature reduction peak, Plow-temp peak, at a temperature of 300-500° C. to the peak height of the high-temperature reduction peak, Phi-temp peak, at a temperature of 650-850° C., i.e. S=Plow-temp peak/Phi-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： Described are a process and a system for processing aromatics-rich fraction oil. The process includes: (1) introducing an aromatics-rich fraction oil into a fifth reaction unit for hydrosaturation, followed by fractionation, to provide a first light component and a first heavy component; (2) introducing a deoiled asphalt and an aromatics-comprising stream including the first heavy component into a hydrogen dissolving unit to be mixed with hydrogen, and introducing the mixed material into a first reaction unit for a hydrogenation reaction; (3) fractionating a liquid-phase product from the first reaction unit to provide a second light component and a second heavy component; (41) introducing the second light component into a second reaction unit for reaction; and (42) introducing the second heavy component into a delayed coking unit for reaction; or using the second heavy component as a component of low sulfur ship fuel oil.
