Embodiment 1

[0026] Put an appropriate amount of small balls with a diameter of φ1~2mm γ-Al 2 O 3 The carrier (Catalyst Plant of Fushun Petrochemical Company) was roasted in a muffle furnace at 1100°C for 4 hours. After cooling, it was used as a carrier for subsequent catalysts. 95%, the specific surface area is 101m 2 / g.

Embodiment 2

[0028] Weigh 165 grams of the alumina carrier prepared in Example 1, and use 119.3 grams of nickel nitrate Ni[(NO 3 ) 2 ·6H 2 O] and 115.5 ml of distilled water were immersed in an equal volume for 2 hours. After preliminary drying at room temperature, the catalyst A was prepared by vacuum drying at a constant temperature of 160°C for 7 hours to prepare a catalyst A with a metal Ni loading of 14.6%wt.

Embodiment 3

[0030] Put 130 grams of γ-Al balls with a diameter of φ1~2mm without high temperature treatment 2 O 3 The carrier (catalyst plant of Fushun Petrochemical Company) was prepared according to the method of Example 2 to prepare the catalyst contrast agent B with the same Ni metal content.

Abstract

A selective hydrocatalyst wit high hydrogenating activity, selectivity and stability for the low-temp selective hydrogenation of diene is composed of the carrier gamma-Al2O3 calcined at 900-1200 deg.C and the active component Ni (5-25 Wt %). Its low-temp preparing process is also disclosed.

Description

Technical field [0001] The invention relates to a diene selective hydrogenation catalyst and a preparation method thereof, in particular to a catalyst used for catalytic cracking of light gasoline or C 5 The catalyst for selective hydrogenation of the distillate under low-temperature reaction conditions and its preparation method. Background technique [0002] The content of olefins in FCC gasoline is relatively high, generally 30 to 60% by volume. In order to improve and improve the quality of motor gasoline, further processing is required to reduce the content of olefins. The current processing technology must use strong acid catalysts or acid carriers to convert olefins into high-octane non-olefin components, such as catalytic cracking light gasoline (dry point less than 75 ℃ or less than 100 ℃, hereinafter referred to as catalytic light Gasoline) or C 5 The olefins in the distillate are etherified with methanol or ethanol under the action of a strong acid resin catalyst to pr...
