Composite diesel and preparation process thereof

Abstract

The invention discloses a composite diesel composed of the following components, by weight: diesel, dimethyl carbonate, turpentine, n-hexane, isobutanol, naphthenic acid, kerosene, coal tar and heavy aromatics. With the composite diesel, composite diesel dynamic performance is improved, and functions of reducing nozzle carbon deposition, suppressing smoke and supporting combustion are realized. With dimethyl carbonate, combustion smoke of a diesel engine can be greatly reduced or substantially eliminated, environment pollution caused by diesel combustion can be reduced, and the heat engine efficiency of the diesel engine can be improved.

Description

Technical field

[0001] The present invention involves the field of petroleum, which specializes in a composite diesel, and also involves a composite diesel manufacturing process. Background technique

[0002] As a non -renewable resource, excessive development and use, especially on vehicle fuel, have caused serious pollution of the environment. If the current consumption speed is calculated in the near future, oil resources will be exhausted in the future.Under the current severe situation, synthetic diesel as a car fuel replacement resource can effectively reduce the amount of oil use, reduce the pollution of the environment, and reduce the cost of fuel.However, the current development of composite diesel projects has not made great breakthroughs. There are mainly problems such as poor dynamicity, poor mutual solubility, low flash point, insufficient combustion, and high price, which has always hindered the development of composite diesel.
