Embodiment 1

[0039] The catalyst was prepared by impregnation method, and the carrier was doped Co 2+ For MCM-41, the doping amount of Co2+ in MCM-41 is controlled at 0.65% of the mass of the carrier. The active component molybdenum nitride MO 2 N, tungsten nitride W 2 N, molybdenum carbide Mo 2 The total content of C and tungsten carbide WC is 10% of the mass of the carrier, and the molar ratio thereof is 1:0.4:0.3:0.8.

[0040] The catalyst is loaded into a fixed bed reactor, the reaction tube of the reactor is made of stainless steel with an inner diameter of 50 mm, the catalyst bed temperature is measured with a UGU808 temperature control meter, and the raw material light oil is manufactured by Beijing Satellite Manufacturing Plant The double-plunger micropump continuously transports the hydrogen gas from a high-pressure cylinder and controls the flow rate with a Beijing Qixing Huachuang D07-11A / ZM gas mass flow meter. The catalyst loading is 2kg. The reacted product is cooled in a...

Embodiment 2

[0045] The catalyst is prepared by impregnation method, the carrier is MCM-41 doped with Co2+, and the doping amount of Co2+ in MCM-41 is controlled at 0.7% of the carrier mass. The active component molybdenum nitride MO 2 N, tungsten nitride W 2 N, molybdenum carbide Mo 2 The total content of C and tungsten carbide WC is 10% of the weight of the carrier, and the molar ratio thereof is 1:0.6:0.45):1.2.

[0046] All the other conditions are the same as in Example 1.

[0047] The final product was tested and its research octane number was still 93.9, while the total sulfur content was reduced to 2ppm.

Embodiment 3

[0072] The catalyst contains catalytic promoter Cr 2 o 3 , ZrO 2 , CeO 2 , V 2 o 5 and NbOPO 4 , its content is respectively 1%, 2%, 1.5%, 1% and 3%, all the other are identical with embodiment 1.

[0073] The final product was tested, and after 3 months of use, the pressure drop of the catalyst bed did not change, which was 14.8% lower than the pressure drop of the catalyst bed in Example 1 for the same use time.

Abstract

The invention discloses a hydrodesulfurization catalyst. The catalyst contains a carrier and an active ingredient, wherein the carrier is MCM-41, of which a synthesized skeleton structure is doped with heteroatoms Co<2+>, and the doped amount of the heteroatoms Co<2+> is 0.56% to 0.75 the weight of the MCM-41; and the active ingredient is a mixture of dimolybdenum nitride MO2N, tungsten nitride W2N, molybdenum carbide Mo2C and tungsten carbide WC, and the total content of the active ingredient is 1% to 15% the weight of the carrier MCM-41. The catalyst further contains a catalytic promoter, wherein the catalytic promoter is a mixture of Cr2O3, ZrO2, CeO2, V2O5 and NbOPO4. By the catalyst, the total sulfur content of FCC gasoline can be lowered to be lower than 10ppm, so as to meet national gasoline standards V. Meanwhile, by the catalyst, the octance value of the FCC gasoline cannot be lowered obviously.

Description

technical field [0001] The invention relates to the technical field of catalysts, in particular to a hydrodesulfurization refining catalyst, more preferably to a catalyst for hydrodesulfurization of FCC gasoline and reducing the range of octane number reduction. Background technique [0002] In the 21st century, the demand and use of fuel oil have increased significantly, and the environmental pollution caused by sulfur compounds in it has attracted people's attention. Sulfur oxides (SO x ) into the air, producing acid rain and sulfuric acid smog pollution, etc., resulting in air pollution. [0003] Sulfur is a harmful substance that exists in gasoline in nature. More than 80% of the sulfur in finished gasoline comes from catalytic cracking (FCC) gasoline. As crude oil continues to become heavier, the sulfur content in FCC gasoline will continue to increase. Foreign gasoline generally comes from FCC (34%), catalytic reforming (33%), and alkylation, isomerization and etheri...
