specific Embodiment approach 1

[0024] Specific embodiment one: the present embodiment composite environmental protection fuel oil agent is made of ethylene light tar (PFO), isooctyl alcohol (2-ethylhexanol), national standard diesel oil, dialkoxyalkane (DAAK) and diboron trioxide (B 2 o 3 ) is prepared by reacting in a volume ratio of 3:1:3:2:1;

[0025] Composite environment-friendly fuel oil agent is prepared according to the following steps:

[0026] 1. Mix ethylene light tar (PFO), isooctyl alcohol (2-ethylhexanol), national standard diesel oil, dialkoxyalkane (DAAK) and di Boron (B 2 o 3 ) into the reactor, and add catalyst and additives to the reactor for oxidation reaction for 40±5min. During the oxidation reaction, the exothermic temperature is controlled to be 100±5°C, and the endothermic temperature is controlled to be 120±5°C; wherein the catalyst is diethanolamine (2 '-dihydroxydiethylamine), the additive is di-n-pentyl ether and ethylene-vinyl acetate copolymer, and the volume ratio of di-...

specific Embodiment approach 2

[0040] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the volume ratio of the oxidation reaction product in Step 1 of the preparation method to the carrier solvent in Step 2 of the preparation method is 10:3. Other steps and parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0041] Specific implementation mode three: the composite type environment-friendly fuel oil agent of this implementation mode is prepared according to the following steps:

[0042] 1. Mix ethylene light tar (PFO), isooctyl alcohol (2-ethylhexanol), national standard diesel oil, dialkoxyalkane (DAAK) and di Boron (B 2 o 3 ) into the reactor, and add catalyst and additives to the reactor for oxidation reaction for 40±5min. During the oxidation reaction, the exothermic temperature is controlled to be 100±5°C, and the endothermic temperature is controlled to be 120±5°C; wherein the catalyst is diethanolamine (2 '-dihydroxydiethylamine), the additive is di-n-pentyl ether and ethylene-vinyl acetate copolymer, and the volume ratio of di-n-pentyl ether and ethylene-vinyl acetate copolymer is 1:1;

[0043] 2. Complexation: pump the oxidation reaction product of step one into the complexation reactor, then add peroxide catalyst according to 2% ± 0.01% of the volume of the oxidation re...

Abstract

The invention discloses a compound-type environmentally-friendly fuel oil solution and a preparation method thereof and relates to a fuel oil solution and a preparation method thereof, which can be used for solving the problems that only a fuel oil additive with a single function can be produced in our country; the manufacturing process is not environmentally friendly; a high-quality fuel oil additive mainly depends on import to be obtained; the high-quality fuel oil additive product at abroad is synthesized by adopting a process method of blending, emulsification and sulfonation; the productive process is complex; the operation is not safe; the produced product performance is not stable; and poisonous and harmful substances such as sulfide, acid and the like are generated in the production and use processes. The compound-type environmentally-friendly fuel is prepared by the following step: 1. carrying out catalyzed oxidation; 2. complexing; 3. refining; and 4. filtering and standing. The invention relates to the production field of fuel oil and product oil.

Description

technical field [0001] The invention relates to a fuel oil agent and a preparation method thereof. Background technique [0002] Petroleum and fuel oil series products must be added with various additives according to my country's environmental protection and energy-saving policies. The use of fuel additives can increase engine power, reduce oil release, purify engine emissions, and reduce pollution without changing the structure of vehicles and engines. However, domestic enterprises can only use traditional blending, emulsification, and sulfonation production processes to produce ordinary anti-riot agents, antioxidants, lubricants, stabilizers, or cetane number increasers with a single function, but the effect is not good. Ideal, all can not achieve the double effect of energy saving and purification at the same time. Cause fuel oil additive to use loaded down with trivial details, and cost is high. Moreover, the existing domestic manufacturing processes of various fuel o...
