Embodiment 1

[0015] A methanol-gasoline additive consisting of methanol and a modifying agent in a weight ratio of 92:8, wherein the modifying agent is composed of substances in the following weight ratios:

[0016]

[0017]

[0018] Put the substances constituting the modifier into the reaction kettle according to the weight ratio, and add methanol at the same time, heat to 55°C, react for 30 minutes, filter, and the clear liquid is the methanol gasoline additive.

Embodiment 2

[0020] A methanol-gasoline additive consisting of methanol and a modifier in a weight ratio of 97:3, wherein the modifier is made of the following substances in the weight ratio:

[0021]

[0022] Put the substances constituting the modifier into the reaction kettle according to the weight ratio, add methanol at the same time, heat to 50°C, react for 45 minutes, filter, and the clear liquid is the methanol gasoline additive.

Embodiment 3

[0024] A methanol-gasoline additive consisting of methanol and a modifier in a weight ratio of 95:5, wherein the modifier is made of the following substances in the weight ratio:

[0025]

[0026] Put the substances constituting the modifier into the reaction kettle according to the weight ratio, and add methanol at the same time, heat to 52°C, react for 40 minutes, filter, and the clear liquid is the methanol gasoline additive.

[0027] The methanol gasoline additive prepared in the above examples is uniformly mixed with finished gasoline in any proportion to obtain methanol gasoline of different labels, such as M15, which can be mixed with 15 parts of methanol gasoline additive and 85 parts of finished gasoline.

[0028] Get the methanol gasoline that each embodiment methanol gasoline additive obtains, compare under the same operating conditions (same engine runs the same time at the same speed) with finished gasoline, the result is as follows:

Abstract

The invention discloses a methanol gasoline additive. The methanol gasoline additive comprises methanol and modifying agent in a weight ratio of (92-97):(3-8), wherein the modifying agent comprises the following materials in percentage by weight: 15-25% of isobutanol, 10-20% of oleic acid, 18-22% of dimethyl carbonate, 7-13% of dimethyl ether, 1-3% of methyl tertiary butyl ether, 12-18% of diethyl ether, 9-11% of acetone, 3-7% of tertiary butanol, 0.8-1.2% of hexamine, and 1.6-2.4% of benzotriazole. The invention further discloses a preparation method for the additive. According to the methanol gasoline additive and the preparation method for the additive provided by the invention, the mutual synergistic effect of a plurality of organic substances is adopted, so that the additive effectively disperses various hydrocarbons in the finished product gasoline, the combustion process is complete and sufficient for reducing the oil consumption by about 6.5-9.8%, reducing the content of CO in the exhausted tail gas by about 40%, and reducing the content of the hydrocarbon compound by about 60%.

Description

technical field [0001] The invention relates to the technical field of gasoline additives, especially methanol gasoline additives, and a preparation method thereof. Background technique [0002] Improving the cleanliness of gasoline for vehicles and making gasoline fully combustible are issues of great concern to the chemical industry and the automobile industry. Especially in the gasoline currently used in my country, the proportion of catalytic cracked gasoline is still quite high, so the rubber produced by gasoline oxidation The problems of quality, paint film and deposits are still relatively serious. To solve this problem, in addition to producing clean gasoline with reduced olefin content in refineries, adding additives to finished gasoline is also a common method in the chemical industry at home and abroad; although there are many reports mentioning gasoline additives, none of them can effectively reduce gasoline consumption. . Contents of the invention [0003] Ai...
