摘要： A hydrodesulfurization catalyst used for hydrodesulfurization of catalytically cracked gasoline comprises a support composed mainly of alumina modified with an oxide of at least one metal selected from the group consisting of iron, chromium, cobalt, nickel, copper, zinc, yttrium, scandium and lanthanoid-based metals, with at least one metal selected from the group consisting of Group 6A and Group 8 metals loaded as an active metal on the support. Hydrogenation of olefins generated as by-products during hydrodesulfurization of the catalytically cracked gasoline fraction, as an important constituent base of gasoline, can be adequately inhibited to maintain the octane number, while sufficiently reducing the sulfur content of the hydrodesulfurized catalytically cracked gasoline fraction.

摘要： The gas oil fraction hydrotreatment process of the invention is characterized by using a gas oil fraction with a sulfur content of 0.8-2% by mass and a total aromatic content of 20-35% by volume as the feed oil and subjecting the feed oil to hydrotreatment in the presence of a hydrogenation catalyst comprising at least one metal from among Group 6A metals and at least one metal from among Group 8 metals as active metals, and under reaction conditions with a reaction temperature of 330-390° C., a hydrogen partial pressure of 12-20 MPa and a liquid hourly space velocity of 0.1-1 h−1, to obtain an ultralow sulfur and low- aromatic gas oil fraction having a sulfur content of not greater than 1 ppm by mass and a total aromatic content of not greater than 1% by volume. This hydrotreatment process allows production of a “zero sulfur” and “zero aromatic” gas oil fraction in an efficient and reliable manner without provision of special operating conditions or equipment investment.
