Example Embodiment

[0030] Example 1

[0031] An oil-soluble octano-molybdenum catalyst provided by this example and the preparation method thereof, including the following steps:

[0032] 1) A mixture of molybdated acid, acetic anhydride, and isotoic acid in molar ratio of 1: 2: 4, and mix well by electromagnetic stirrer to obtain a mixture;

[0033] 2) Under stirring, the mixture is heated to 70 ° C, and the reaction is 1 h;

[0034] 3) Heating under vacuum, removes the acetic acid of the sub-reactive product;

[0035] 4) Heating to 150 ° C continued to react 2 h, and the oil-soluble hydrothermolybdenum catalyst can be obtained after the reaction.

Example Embodiment

[0036] Example 2

[0037] An oil-soluble octano-molybdenum catalyst provided by this example and the preparation method thereof, including the following steps:

[0038] 1) Ammonium molybdenate, acetic anhydride, isochinic acid, to ensure molybdenum atom, acetic anhydride, and isteric acid in molar ratio 1: 3: 5, mix well by electromagnetic stirrer, resulting in a mixture;

[0039] 2) Under the action of stirring, heating the mixture to 80 ° C, reacting 1.5 h;

[0040] 3) Heating under vacuum, removes the acetic acid of the sub-reactive product;

[0041] 4) Heating to 160 ° C continued to react 2H, and the oil-soluble hydrothermolybdenum catalyst can be obtained after the reaction.

Example Embodiment

[0042] Example 3

[0043] The catalyst prepared in the above examples is used in the hydrocracking reaction of the Middle Eastern reducing residue, and the MO / NI compound catalyst prepared by the metal Ni is added (MO: Ni = 1: 1) in the same conditions. Next, the reaction temperature is 432 ° C, the reaction pressure is 12 MPa, the reaction time is 60 min, and the catalyst is 150 ppm (in the active metal total meter), the material properties are shown in Table 1, the test product distribution is shown in Table 2:

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. [0003] ...
