Embodiment 1
[0018] Example 1 35kg of nitromethane, 20kg of methanol, 10kg of cyclohexanone, 2kg of monoethanolamine and 33kg of ethylene glycol monomethyl ether were mixed to obtain an additive. The technical indicators and testing standards of the additive are shown in Table 1.
Embodiment 2
[0019] Embodiment 2 uses naphtha produced in Daqing as a raw material, and its research method octane number is determined to be 50. After mixing 75kg of Daqing naphtha and 25kg of the additive prepared in Example 1, an equivalent research method octane number can be obtained. 90# high-grade gasoline.
Embodiment 3
[0020] Example 3 35kg of nitromethane, 26kg of methanol, 7kg of cyclohexanone, 1kg of monoethanolamine, and 31kg of ethylene glycol monomethyl ether were mixed to obtain an additive.

The invention relates to an additive for producing high-grade gasoline using naphtha and the high grade gasoline comprising raw materials of the following constituents (by weight proportion): nitromethane 25-40%, methanol 20-30%, cyclohexanone 8-10%, monoethanol-amine 1-2%, mono methoxy polyethylene 30-45%. The weight ratio of each raw materials in the gasoline is benzine naphtha : catalyst =60-75 : 25-40.
Description
technical field [0001] The invention belongs to the technical field of fuel oil processing, in particular to an additive for producing high-grade gasoline from naphtha and the high-grade gasoline. Background technique [0002] Naphtha is straight-run low-octane gasoline in the refining process. It is called naphtha in foreign countries and naphtha in China. It is a colorless and transparent liquid and is one of the petroleum fractions. It has high alkane and cycloalkane content. , good stability, low heavy metal content, low sulfur content, and low toxicity. Naphtha is generally the light fraction distilled from crude oil under certain conditions by initial distillation and atmospheric distillation, or the gasoline fraction obtained by hydrotreating secondary processed gasoline. The boiling range is generally from the initial boiling point to 220°C. Naphtha is generally used as a raw material for the production of ethylene or aromatics. It requires high cost consumption to ...
