Abstract

A composite additive for diesel comprises, by weight, 30-70 parts of fatty acid methyl ester, 15-30 parts of animal and vegetable oil, 5-40 parts of n-pentanol, 5-40 parts of n-octanol, 0.1-1.4 partsof alkylbenzene, 2-5 parts of copper sulfate, 2-6 parts of xylene, 0.08-0.8 part of diester of thiodipropionic acid and 0.2-0.6 part of polyisobutylene. A preparation method of the composite additivefor diesel comprises the following steps: sequentially adding above raw materials are sequentially added to the into a reaction kettle according to corresponding weight parts, performing stirring under condensation refluxing conditions for 10-30 min, and performing full and uniform mixing; and (3) standing the obtained material for 6-7 h to obtain the environmentally-friendly additive for diesel.The composite additive for diesel has the advantages of simple extraction process, low device requirements, increase of the yield by refluxing, shortening of the generation period by reducing the standing time, provision of a support for industrial synthesis, improvement of the diesel efficiency and reduction of exhaust emission.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and energy saving, and in particular relates to a diesel compound additive and a preparation method thereof. Background technique [0002] Since the automobile engine came into the market, in order to improve the combustion efficiency of the engine, people are trying to improve the compression ratio of the automobile engine. From 4.0 to 10.8, the compression ratio is gradually increased to 10.8. Although the combustion efficiency is increased, the power is also reduced. The current international engine compression ratio is basically set within the range of 8.0. To achieve this goal, various methods have been adopted both at home and abroad to increase the octane number of diesel to meet the requirements of the engine's compression ratio. [0003] The more widely used method is to mix a small amount of anti-knock additives in diesel oil. The anti-knock agent that was adopted in t...
