Embodiment 1

[0031] A kind of oil-soluble molybdenum octoate catalyst provided by the present example and preparation method thereof, comprises the steps:

[0032] 1) Add molybdic acid, acetic anhydride, and isooctanoic acid into the container at a molar ratio of 1:2:4, and mix them uniformly with an electromagnetic stirrer to obtain a mixed solution;

[0033] 2) Under the action of stirring, heat the mixture to 70°C and react for 1 hour;

[0034] 3) heating under vacuum to remove by-reaction product acetic acid;

[0035] 4) Heating to 150° C. to continue the reaction for 2 hours, and the oil-soluble molybdenum octanoate catalyst can be prepared after the reaction is completed.

Embodiment 2

[0037] A kind of oil-soluble molybdenum octoate catalyst provided by the present example and preparation method thereof, comprises the steps:

[0038] 1) Take ammonium molybdate, acetic anhydride, and isooctanoic acid and add them to the container to ensure that molybdenum atoms, acetic anhydride, and isooctanoic acid are added to the container at a molar ratio of 1:3:5, and mix evenly with an electromagnetic stirrer to obtain a mixed solution;

[0039] 2) Under the action of stirring, heat the mixture to 80°C and react for 1.5h;

[0040] 3) heating under vacuum to remove by-reaction product acetic acid;

[0041] 4) Heating to 160° C. to continue the reaction for 2 hours, and the oil-soluble molybdenum octanoate catalyst can be prepared after the reaction is completed.

Embodiment 3

[0043] The catalyst prepared in the above examples was used in the suspended bed hydrocracking reaction for slagging reduction in the Middle East, and a blank Mo / Ni composite catalyst (Mo:Ni=1:1) prepared by adding metal Ni was used under the same conditions For comparison, the reaction temperature is 432°C, the reaction pressure is 12MPa, the reaction time is 60min, and 150ppm of catalyst (in terms of active metal total amount) is added. The properties of raw materials are shown in Table 1 below, and the distribution of test products is shown in Table 2 below:

Abstract

The invention discloses an oil-soluble molybdenum caprylate catalyst as well as a preparation method and application thereof. The prepared molybdenum caprylate catalyst is good in dispersity and high in active metal content, can be used for hydro-conversion of inferior heavy oil, residual oil, oil sand and asphalt, can also be used for coal / oil co-refining, and can effectively inhibit coke formation in the reaction process and guarantee long-period operation of a device.

Description

technical field [0001] The invention relates to an oil-soluble molybdenum octanoate catalyst used for hydrocracking of inferior heavy oil, residual oil and kerosene co-refining, especially the preparation and application of the oil-soluble molybdenum octanoate catalyst. Background technique [0002] In recent years, crude oil has become increasingly heavy and inferior, and environmental protection requirements have become increasingly stringent. How to use limited oil resources cleanly and efficiently to meet the growing market demand for light and middle distillates has become a challenge for the petroleum processing industry in the world today. important task. Due to its high conversion rate of heavy oil, strong adaptability of raw materials, and clean products, the suspended bed hydrogenation process is widely used in the fields of low-quality heavy oil, residual oil, coal tar hydrogenation, and kerosene co-refining. , The attention of coal chemical companies.
