Embodiment 1

[0024] A clean gasoline using naphtha as a raw material, prepared by parts by weight of the following components:

[0025]

[0026] A method for preparing clean gasoline using naphtha as a raw material, the specific steps are as follows:

[0027] (1) According to the octane number of naphtha, pump naphtha and C according to the formula ratio under normal temperature and pressure. 5 Solvent oil, C 9 Solvent oil is injected into a closed blending tank;

[0028] (2) Use a pump to pump in the proportioned methyl naphthalene, mixed benzene, and ethylene glycol dimethyl ether into the blending tank, and stir for 12 minutes to mix evenly;

[0029] (3) Inject nitromethane, polyisobutadiene ethylene diamine, polyisobutyl carbamic acid isobutyl ester, ethylene glycol dimethyl ether, and octadecamido group into the mixing tank. Ferrocene and methylcyclopentadiene manganese tricarbonyl, stir for 18 minutes and mix well;

[0030] (4) The mixed solution prepared by the above steps is thoroughly stir...

Embodiment 2

[0034] A clean gasoline using naphtha as a raw material is prepared by weighing and adjusting the following raw materials, and the parts are all parts by weight.

[0035]

[0036] A method for preparing clean gasoline using naphtha as a raw material, and the specific operation steps are the same as in Example 1.

[0037] The naphtha is a naphtha with a research octane number of 60.

[0038] The nitromethane is preferably a commercially available product in which the C atom is bonded by sp3 hybrid orbital, and the N atom is bonded by sp2 hybrid orbital, and the molecular formula is CH3NO2.

[0039] The clean gasoline prepared in Example 1 was numbered A, and the clean gasoline prepared in Example 2 was numbered B. Under the same conditions, the run, water content, colloid, copper corrosion, mechanical impurities and other items were tested. The results are compared with the performance indicators of the existing 93# gasoline.

Abstract

The invention belongs to the technical field of petrochemical fuel oil processing and especially relates to a formula and preparation method of clean gasoline using naphtha as one of raw materials. The preparation method is that naphtha is used as raw material and C5 solvent oil, C9 solvent oil, methylnaphthalene, mixed benzene and dimethoxyethane are added according to a ratio, thus the firing behavior, octane number and boiling range of naphtha can be improved and increased under synergy. The raw materials of the clean gasoline are simple, common and economical and the clean gasoline has cost benefit.

Description

Technical field [0001] The invention belongs to the technical field of petrochemical fuel oil processing, and particularly relates to a formula for producing clean gasoline using naphtha as a raw material and a preparation method thereof. Background technique [0002] Oil is a non-renewable resource. With the increase in energy demand for economic development, oil reserves are declining. And with the improvement of environmental protection requirements, the requirements for oil quality are also increasing, and there is an urgent need to improve the utilization rate and environmental performance of petroleum resources. [0003] Naphtha is an easily volatile light oil product, which is obtained from crude oil distillation or petroleum secondary processing to obtain corresponding fractions. At present, naphtha is mainly used in tube furnace cracking to produce ethylene and propylene, and catalytic reforming to produce benzene, toluene, xylene, etc. However, due to the lighter compon...
