Title:
BIFUNCTIONAL CATALYST FOR DEEP DESULFURIZATION AND IMPROVING QUALITY OF GASOLINE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/155721
Kind Code:
A1
Abstract:
Provided are a bifunctional catalyst for deep desulfurization and improving the quality of gasoline, a preparation method therefor and the use thereof. The bifunctional catalyst contains a catalyst carrier subjected to a modification treatment, and a supported active metal, wherein the catalyst carrier subjected to a modification treatment is a rare earth element-modified γ-Al2O3 carrier, or the catalyst carrier subjected to a modification treatment is obtained by mixing γ-Al2O3 and an acidic molecular sieve by means of a binder and calcinating same to give a composite carrier and then modifying the composite carrier with a rare earth element. By means of the bifunctional catalyst for deep desulfurization and improving the quality of gasoline, the deep desulfurization of catalytic cracked gasoline with a high sulfur content can be realized under relatively moderate conditions, and no significant loss of the octane number is ensured.
