Abstract: Provided are a bifunctional catalyst for deep desulfurization and gasoline quality improvement and a preparation method therefore and a use thereof. The bifunctional catalyst includes a modified catalyst and a loaded active metal, where the modified catalyst carrier is a γ-Al2O3 modified with a rare earth element, or the modified catalyst carrier is a composite carrier prepared by mixing and calcinating γ-Al2O3 and an acid molecular sieve through a binder, and then modifying with the rare earth element. The bifunctional catalyst for deep desulfurization and gasoline quality improvement can achieve deep desulfurization of high-sulfur fluid catalytic cracking gasoline, and ensure no significant loss of octane number under relatively mild conditions.

Abstract: Provided are an in situ bifunctional catalyst for deep desulfurization and increasing octane number of gasoline, and its preparation method and application. The bifunctional catalyst includes a modified catalyst carrier and a loaded active metal, where the modified catalyst carrier is a composite carrier prepared through mixing γ-Al2O3 and an acidic molecular sieve by a binder and calcining. When the bifunctional catalyst provided by the present application is used for hydrodesulfurization of gasolines, deep desulfurization, olefin reduction and octane number preservation can be realized simultaneously, thereby obtaining a high-quality oil product.
