Technical Field

The invention belongs to the technical field of additives, and particularly relates to an ethanol gasoline-saving additive and a preparation method thereof.

Background

In recent years, in order to improve the environment, China has started to implement stricter exhaust emission standards, and has also proposed "national six oils" -ethanol gasoline. However, because the calorific value of ethanol is about 33% lower than that of gasoline, compared with the common gasoline, the total calorific value of the ethanol gasoline with the same volume is lower than that of the common gasoline, so the ethanol gasoline has the problems of increased oil consumption and reduced power compared with the common gasoline. Meanwhile, the ethanol gasoline can be separated from each other after being stored for a long time, so that the ethanol and the gasoline are layered.

In 31.12.2019, the national standardization administration committee issued GB 27999-2019 Standard "evaluation method and index for Fuel consumption of passenger cars", which will be implemented from 1.1.2021. The average fuel consumption of the passenger car in China is reduced to 4L/100km (NEDC working condition) in 2025 years, and the corresponding carbon dioxide emission is about 95g/km (NEDC working condition).

The research and development of the fuel economy of the ethanol gasoline vehicle can improve the fuel-saving effect of the oil products on the vehicle, enhance the experience of a client terminal, slow down the dependence of China on imported petroleum, keep the continuous and stable development of the national economy, and improve the air quality of large and medium-sized cities, thereby having important significance and reducing the fuel cost of automobile consumers. Therefore, the ethanol gasoline saving development task is urgent.
