Biogasoline additive and preparation method and application thereof

Abstract

The invention relates to a biogasoline additive and its preparation method and application. The invention aims to provide a low-cost biogasoline additive capable of raising isooctane value of gasoline, enhancing anti-detonating quality, reducing pollutant emission, decreasing PM2.5 and improving gasoline combustion efficiency. The biogasoline additive is prepared and applied by the following steps: adding ferment and methyl tert-butyl ether into an alcoholic solvent, heating to 30-40 DEG C, stirring to prepare the biogasoline additive, adding the biogasoline additive which accounts for 0.09-0.5% of the total weight of gasoline into the gasoline, uniformly stirring, and standing at normal temperature for 3-5h for usage.

Description

technical field

[0001] The invention relates to the field of additives for improving gasoline quality, in particular to a bio-gasoline additive and its preparation method and application. 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. Therefore, gasoline is oxidized to produce colloids, The problem of paint film and sediment seriously affects air pollution, aggravates the generation of PM2.5, and affects people's normal life.

[0003] In refined oil, in order to solve the above problems, in addition to producing clean gasoline with reduced olefin content in the refinery, it is also necessary to add additives to ensure sufficient combustion of gasoline and reduce pollutant emissions. At present, for exam...
