Embodiment 1

[0022] A B5 biodiesel blended fuel, whose volume percentage is composed of: 0# diesel oil 94.9%, ethyl levulinate 4%, biodiesel 1%, cosolvent 0.05%, cetane number improver 0.05%.

[0023] The preparation method is as follows: (1) Mix ethyl levulinate and biodiesel according to volume percentage to form a mixed solution, and then add co-solvent and cetane number enhancer in sequence; (2) Mix the mixed solution in step (1) in When stirring, add 0# diesel oil and mix well to get blended fuel. This fuel is indicated by E4B1.

Embodiment 2

[0025] A B5 biodiesel blended fuel, which is composed of 94.93% by volume of 0# diesel oil, 3% ethyl levulinate, 2% biodiesel, 0.03% co-solvent, and 0.04% cetane number enhancer.

[0026] The preparation method is the same as in Example 1. This fuel is indicated by E3B2.

Embodiment 3

[0028] A B5 biodiesel blended fuel, which is composed of 94.94% by volume of 0# diesel oil, 2.5% of ethyl levulinate, 2.5% of biodiesel, 0.03% of cosolvent, and 0.03% of cetane number improver.

[0029] The preparation method is the same as in Example 1. The fuel is indicated by E2.5B2.5.

Abstract

The invention belongs to the technical field of biomass energy and particularly relates to a B5 biodiesel blending fuel and a preparation method thereof. The fuel comprises, by volume, 94-95% of 0# diesel, 2-4% of ethyl levulinate, 1-3% of biodiesel, 0.03-0.05% of latent solvent and 0.01-0.05% of cetane number improving agent. Physicochemical properties and power performance of the fuel can meet GB / T25199-2010 'biodiesel blending fuel (B5)'. The emission ratio of pollutants such as soot, carbon monoxide, carbon dioxide and nitrogen oxide which are generated through burning of the fuel in a diesel engine is lower than that of pollutants which are generated through burning of diesel, the fuel can be widely used in vehicle diesel engines and energy-saving and emission-reduction can be achieved.

Description

technical field [0001] The invention belongs to the technical field of biomass energy, and in particular relates to a B5 biodiesel blended fuel and a preparation method thereof. Background technique [0002] my country's per capita oil resources are only one-tenth of the world's average level. With the rapid development of my country's economy, the demand for oil is increasing, and the contradiction between economic development and resource shortage is becoming increasingly prominent. In 2011, my country imported 250 million tons of crude oil, and its dependence on foreign oil reached 55.2%. Since 2009, my country's dependence on foreign oil has exceeded the "international warning line" of 50%. It is expected that the foreign dependence will reach more than 65% in 2020. Vehicle fuel consumption accounts for nearly 55% of petroleum consumption, and increases by about 15% every year. In 2020, vehicle fuel consumption is expected to reach 65% of national petroleum consumption. ...
