Abstract
The present invention relates to a production process of lead-free gasoline No. 90 by using pyrolysis gasoline. By weight, aluminium muriate whose weight percentage is 1.5-5% of that of the pyrolysis gasoline is added to the pyrolysis gasoline, distilled to 140-205 deg. C, then passed through such processes of blending, caustic neutralizing, washing by water, filtering and adding antixidant to obtain the invented product. Its production process is simple and convenient, and practical.
Description
The present invention relates to the chemical oil refining field, particularly produces the production method of No. 90 white gasolinees with pyrolysis gasoline.
The pyrolysis gasoline raw material sources are very abundant, because it is higher to contain amount of gasoline, use so often served as normal benzene by some, but harm is very big: the pyrolysis gasoline olefin(e) centent is higher, easy at normal temperatures deterioration by oxidation, during high-temp combustion, generate a large amount of peralcohol, caused colloid, bitum acceleration to generate, cause in the combustion chamber carbon deposit serious, stop up inlet valve, influence the works better of firing system, and even cause stop off.
The present invention is exactly at the problems referred to above, provide a kind of simple and practical be the method for No. 90 gasoline of raw material production with the pyrolysis gasoline.
The object of the present invention is achieved like this: the present invention just is by weight, add in the pyrolysis gasoline to account for 1.5 of pyrolysis gasoline～5 ‰ aluminum chlorides, after being distilled to 140 ℃～205 ℃ then, again through blending, alkali neutralizes, wash, filter, after adding oxidation inhibitor.
Major advantage of the present invention:
Production technique of the present invention is to react as catalyzer with aluminum chloride under normal pressure, under temperature lower (140 ℃～205 ℃) condition, reaction is after distillation tower, common process can be produced standard compliant No. 90 white gasolinees, so production technique is easy, practical.
Embodiment 1:
By weight, add in the pyrolysis gasoline to account for 1.5 of pyrolysis gasoline～5 ‰ aluminum chlorides, reacted 4～8 hours, input distillation tower in reaction back is when temperature rises to 75.5 ℃, can steam 10% gasoline, when temperature rises to 91 ℃, can steam 50% gasoline, when temperature rises to 120 ℃, can steam 90% gasoline, rise to 140 ℃～205 ℃ in temperature and be the dry point interval.Owing to should distillate 10% in the time of 70 ℃, and in fact 75.5 ℃ just distillate 10%, to concoct with the gasoline that distills before 70 ℃ through the gasoline that heats up in a steamer eventually behind the interval, neutralize with sodium hydroxide then, free sodium hydroxide, low molecular organic acids and some other impurity in the gasoline is removed in washing again, again after filtering, add 0.3～0.5% oxidation inhibitor 501 No. 90 white gasolinees.
Embodiment 2:
The add-on of the aluminum chloride among the embodiment 1 is changed into by weight, add in the pyrolysis gasoline with the aluminum chloride that accounts for 2 of pyrolysis gasoline～4 ‰, temperature rises to 140 ℃～170 ℃ for heating up in a steamer interval temperature eventually, and all the other conditions are constant.
Claims (2)
1, the method for producing No. 90 gasoline with pyrolysis gasoline adds in the pyrolysis gasoline to account for 1.5 of pyrolysis gasoline～5 ‰ aluminum chlorides by weight, be distilled to 140 ℃～205 ℃ then after, again through blending, alkali neutralize, wash, filter, after adding oxidation inhibitor.
2, method of producing No. 90 gasoline with pyrolysis gasoline according to claim 1 is characterized in that adding in the pyrolysis gasoline with the aluminum chloride that accounts for 2 of pyrolysis gasoline～4 ‰, and temperature rises to 140 ℃～170 ℃ distillation range temperature.
