Embodiment 1
[0035] A method for preparing methanol-diesel-biodiesel micro-emulsion fuel oil, comprising the steps of:
[0036] 1) Mix diesel and biodiesel evenly at a volume ratio of 1:1 to obtain the base fuel M0;
[0037] 2) On the basis of 100ml M0, add 5ml methanol to configure the first diesel-biodiesel-methanol microemulsion fuel M5;
[0038] 3) On the basis of 100ml M0, add 10ml methanol and 6ml surfactant to configure the second diesel-biodiesel-methanol microemulsion fuel M10;
[0039] 4) On the basis of 100ml M0, add 10ml methanol and 8ml surfactant to configure the third diesel-biodiesel-methanol microemulsion fuel M15.
[0040] The performances of base fuel M0 prepared above, microemulsion fuel M5 and M10 in emission and combustion are as follows:

Abstract
The invention discloses a method for preparing methanol-diesel oil-biodiesel oil microemulsified fuel oil. The method comprises the steps: 1) uniformly mixing diesel oil and biodiesel oil according tothe volume ratio of 1: 1, so as to obtain base fuel M0; 2) adding 5ml of methanol on the basis of 100ml of M0, so as to prepare a first-kind diesel oil-biodiesel oil-methanol microemulsified fuel M5;3) adding 10ml of methanol and 6ml of surfactant on the basis of 100ml of M0, so as to prepare a second-kind diesel oil-biodiesel oil-methanol microemulsified fuel M10; and 4) adding 10ml of methanoland 8ml of surfactant on the basis of 100ml of M0, so as to prepare a third-kind diesel oil-biodiesel oil-methanol microemulsified fuel M15. According to the method, the emission of soot and CO can be effectively lowered; along with the blending of the methanol, an initial point of the microemulsified fuel can be delayed, a combustion dead point can be advanced, combustion and heat release are centralized, the duration of combustion is short, and the heat release efficiency of the fuel oil is increased.
Description
technical field [0001] The invention relates to a preparation method of vehicle fuel, in particular to a preparation method of a microemulsion novel fuel containing diesel oil, biodiesel and methanol. Background technique [0002] Diesel, also known as oil residue, is an oily product after petroleum refining. It consists of a mixture of different hydrocarbons. Its main components are alkanes, cycloalkanes or aromatics containing 10 to 22 carbon atoms. Its chemical and physical properties are between gasoline and heavy oil, its boiling point is between 170°C and 390°C, and its specific gravity is 0.82~0.845kg / l. [0003] Biodiesel (Biodiesel) refers to a renewable diesel fuel that can replace petrochemical diesel oil, which is made from oil crops, wild oil plants, engineering microalgae and other aquatic vegetable oils, animal oils, and catering waste oils through transesterification processes. Biodiesel is a kind of biomass energy, which is a mono-alkyl ester of long-chai...
