摘要： The present disclosure provides an automatic separation apparatus for four fractions of heavy oil and a separation method thereof, wherein the apparatus includes a solvent reservoir tank (1), a separation unit for four fractions of heavy oil (100) and a receiving apparatus (9). The separation unit for four fractions of heavy oil (100) includes: a filter disc (4) having one end in communication with the solvent reservoir tank (1), and the other end in communication with an inlet of a pre-column flow path switching valve (5); a chromatographic column (6) having an inlet in communication with an outlet of the pre-column flow path switching valve (5), and an outlet in communication with an inlet of a post-column flow path switching valve (8). The receiving apparatus is in communication with an outlet of the post-column flow path switching valve (8).

摘要： The present invention relates to a method for the selective hydrogenation of an unsaturated compound, particularly a method in an unsaturated compound or a mixture containing unsaturated compounds for increase of the light sulphides weight, hydrogenation of a polyunsaturated compound and isomerization of a monounsaturated compound. The method uses a supported catalyst. The supported catalyst contains at least one Group VIB non-noble metal oxide and at least one Group VIII non-noble metal oxide deposited on a carrier; and the catalyst has an optimized acid distribution on the surface of the catalyst, and more preferably has an optimized Group VIII/VIB metal ratio and a Group VIII non-noble metal density per unit of catalyst surface area.
