Abstract

The invention discloses a biodiesel-based mixed diesel which is composed of biodiesel, petroleum light diesel, petroleum heavy diesel and aviation kerosene. The biodiesel comprises a biological base liquid, sodium dodecyl benzene sulfonate, heavy alkylbenzene sulfonate, fatty alcohol polyethenoxy ether ammonium sulfate, acetamide and propanediol. The biological base liquid is composed of palm oil, sunflower seed oil and coconut oil. The invention also discloses a production method of the biodiesel-based mixed diesel, which comprises the following steps: preparing the biological base liquid; preparing the biodiesel; and preparing the mixed diesel. The mixed diesel has the advantages of high flowability, favorable sprayability and high safety, can not easily precipitate, has high comprehensive cost performance in the aspects of power, cleanliness and production cost, and has obvious properties especially in the aspect of cleanliness. Compared with the traditional mixed diesel, the biodiesel-based mixed diesel has the advantages of fewer exhaust emissions and higher environment friendliness, and is suitable for popularization and application.

Description

technical field [0001] The invention relates to a mixed diesel and a production method, in particular to a biodiesel-based mixed diesel and a production method. Background technique [0002] Petroleum diesel is a light petroleum product, a mixture of complex hydrocarbons (about 10 to 22 carbon atoms), used as diesel engine fuel, mainly blended from diesel fractions produced by crude oil distillation, catalytic cracking, thermal cracking, hydrocracking, petroleum coking, etc. It can also be produced from shale oil processing and coal liquefaction, and it is a non-renewable fuel. Petroleum diesel oil is divided into two categories: light diesel oil (boiling point range is about 180-370°C) and heavy diesel oil (boiling point range is about 350-410°C). [0003] Biodiesel is extracted from automatic vegetable oil and is commonly used in tractors, trucks, ships, etc. It is a kind of biomass energy. It is close to petrochemical diesel in physical properties, but its chemical compo...
