Problems solved by technology

[0011] With the development of my country's oil refining technology, domestic white oil has also been recognized by some customers in the market, but the quality and stability of white oil are extremely valued by animal vaccine factories. White oil is an important raw and auxiliary material, and it takes a long time to replace it. , the cost is relatively high. On the other hand, when the relevant departments conduct bidding, due to the stable performance of imported white oil and long application time, most of them choose foreign imported white oil as white oil for veterinary injection, so that domestic white oil is used in the animal vaccine industry. Apps in relatively slow

Embodiment 1

[0034] A kind of production method of veterinary vaccine white oil adjuvant, it comprises the following steps:

[0035] Step 1. Heat the raw oil to 310°C and mix it with hydrogen, introduce it into the first reactor loaded with hydrodesulfurization catalyst I to contact with the catalyst, carry out hydrodesulfurization and denitrogenation reactions under the action of the catalyst, and then react the product A Enter the second reactor loaded with hydrogenation dearomatization catalyst II to carry out hydrogenation dearomatization and hydrogenation saturation reaction with catalyst II, and remove aromatics and unsaturated hydrocarbons in the raw material. Catalyst I is a W-Mo-Ni hydrodesulfurization catalyst with a specific surface area of ​​200m 2 / g, the pore diameter is 25nm, the pore volume is 1.0ml / g, the water absorption rate is 120%, the bulk specific gravity is 0.50g / ml, the infrared acid content is 0.5mmol / g, the ratio of B acid / L acid is 1.8; Catalyst II It is a W-Ni...

Embodiment 2

[0058] A kind of production method of veterinary vaccine white oil adjuvant, it comprises the following steps:

[0059] Step 1. Heat the raw oil to 315°C and mix it with hydrogen, introduce it into the reactor loaded with hydrodesulfurization catalyst I to contact with the catalyst, and carry out hydrodesulfurization and denitrogenation reactions under the action of the catalyst, and the reaction product A enters the reactor loaded with hydrodesulfurization catalyst I. In the reactor of catalyst II, hydrogenation dearomatization and hydrogenation saturation reaction are carried out with hydrogenation dearomatization catalyst II to remove aromatics and unsaturated hydrocarbons in raw materials. Catalyst I is a W-Mo-Ni type hydrodesulfurization catalyst with a specific surface area of ​​180m 2 / g, the pore diameter is 30nm, the pore volume is 0.8ml / g, the water absorption rate is 130%, the bulk specific gravity is 0.60g / ml, the infrared acid content is 0.7mmol / g, the ratio of B ...

Abstract

The invention provides a production method of a veterinary vaccine white oil adjuvant. The method comprises the following steps: 1) heating mineral oil as a raw material, adding the mineral oil into a first reactor, reacting with a hydrodesulfurization catalyst I to obtain a reaction product A, adding into a second reactor to react with a hydrogenation dearomatization catalyst II, and carrying out hydrogenation dearomatization and hydrogenation saturation reaction to obtain a reaction product B; 2) carrying out gas-liquid separation on the reaction product B in the step 1), heating, adding into a third reactor, carrying out hydroisomerization reaction with a hydroisomerization catalyst III, cooling a reaction product C, feeding into a fourth reactor, reacting with a hydrogenation saturation refining catalyst IV for hydrofinishing, and removing unsaturated hydrocarbon in the reaction product C to obtain a reaction product D; and 3) feeding the reaction product D obtained in the step 2) into a fractionation system for product cutting to obtain the veterinary vaccine white oil adjuvants with different viscosities. The veterinary vaccine white oil adjuvant has the advantages of being high in stability, good in animal absorbability, small in animal stress reaction, good in safety and continuous and stable in vaccine antibody.

Description

technical field [0001] The invention belongs to the technical field of petrochemical industry, in particular to a production method of white oil adjuvant for veterinary vaccines. Background technique [0002] White oil is a kind of petroleum product obtained by deep refining to remove impurities such as aromatic hydrocarbons and sulfides in lubricating oil fractions. It is colorless, tasteless, odorless, chemically inert and excellent in light and heat stability. It is widely used in chemical industry , daily necessities, food, medicine, textile and agriculture and other fields. Its main performance indicators are: viscosity, color, easy carbide, ultraviolet absorption, freezing point, etc. my country's white oil is mainly divided into three categories: industrial grade, cosmetic grade, and food and pharmaceutical grade; in 2016, two petrochemical industry standards for light white oil and crude white oil were added, making the classification of white oil grades in my count...
