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.
