Problems solved by technology

[0002] At present, due to the diesel oil produced by small and medium refineries through catalytic cracking and coking, etc., it contains a large amount of sulfur, nitrogen, oxygen heterocyclic compounds, olefin compounds and phenolic substances, which makes the stability of diesel oil poor. After a few days, some Discoloration and turbidity even in one day, and a large amount of colloid and sediment are produced. Non-hydrocarbon compounds, especially non-alkaline oxides, such as pyrrole and tetraoxycarbazole, are very unstable and are easily oxidized into peroxides and cause hydrocarbons. Oxidation, quinolines have an oxidation catalytic effect when non-alkaline oxides coexist, and can accelerate the formation of oxides and the oxidation of hydrocarbons. The above reactions not only deepen the color of diesel oil, but also affect the use value of oil products, and in oil products It will also be accompanied by a large amount of black insoluble colloidal deposits, which will cause blockage of the oil supply pipeline and affect the normal oil supply. This kind of fuel combus

Embodiment 1

[0022] Sulfuric acid (≥98%) 66%

[0023] Absolute Ethanol 26%

[0024] Oleic Acid 8%

Embodiment 2

[0026] Sulfuric acid (≥98%) 68%

[0027] Absolute Ethanol 22%

[0028] Oleic Acid 10%

[0029] The operation process and conditions of the above two embodiments are the same, that is, they are operated under normal temperature and pressure, and after being selected according to any embodiment, they are added to a stirring container, stirred for 5 to 15 minutes, and the oil product decolorizer can be obtained.

[0030] The coked diesel oil produced in a refinery in Puyang, i.e. oxidized diesel oil (black diesel oil), adopts the decolorizing agent provided by the embodiment of the present invention 1, and the dosage is 2%, and the normal temperature and pressure stirring reaction is 2 hours, and the sediment is released. The slag yield is only 2%. The chromaticity is tested according to ASTM D1500 standard, and the result is 2.0, which means the chromaticity reaches the national standard.

Abstract

The invention relates to an oil product decolorizing agent which is composed of sulfuric acid (with a concentration no lower than 98%), anhydrous ethanol, and oleic acid. According to the invention, preparation is operated under normal temperature and normal pressure according to a certain ratio and a certain sequence. The decolorizing agent has the advantages of no three-waste pollution, low cost, easy-to-purchase raw materials, simple process, and convenient application. With the decolorizing agent, oxidized black diesel oil produced during catalytic cracking coking and waste oil and waste rubber oil refining can be decolorized, and a chromaticity can reach a national standard.
