Embodiment 1

[0031] The preparation of embodiment 1 cyanobacteria extract oil

[0032] Spirulina extract oil is prepared according to the following steps:

[0033] (1) The cyanobacteria and the ethanol that the mass fraction is 75% are mixed in the reaction kettle according to the solid-to-liquid ratio (g / ml) 1:10, and ammonium phosphate trihydrate is added, and the addition amount of the ammonium phosphate trihydrate is the weight of the cyanobacteria 0.5%, heating reaction, the reaction conditions are: the temperature is 320 ° C, the pressure is 12 MPa, and the reaction time is 30 min; the reaction solution is obtained;

[0034] Wherein, the solid-liquid ratio (g / ml) of 1:10 refers to mixing according to the ratio of 1g blue-green algae and 10ml of ethanol with a mass fraction of 75%;

[0035] (2) adding absolute ethanol to extract the reaction solution, suction filtration to separate the solid residue, and the liquid phase to stand and stratify into an organic phase and an aqueous etha...

Embodiment 2

[0038] The preparation of embodiment 2 cyanobacteria extract oil

[0039] According to the method described in Example 1, ammonium phosphate trihydrate was replaced by ammonium manganese sulfate hexahydrate, the oil yield of cyanobacteria extracted oil was 27.3%, and the calorific value was 26.0MJ / kg.

Embodiment 3

[0040] The preparation of embodiment 3 cyanobacteria extract oil

[0041] According to the method described in Example 1, ammonium phosphate trihydrate is replaced with a mixture of ammonium phosphate trihydrate and ammonium manganese sulfate hexahydrate in a weight ratio of 1:1; 0.25% of the cyanobacteria, the addition of ammonium sulfate hexahydrate is 0.25% of the blue-green algae weight. The oil yield of cyanobacteria extracted oil is 30.1%, and the calorific value is 27.5MJ / kg.

Abstract

The invention discloses environment-friendly bio-oil and a preparation method thereof. The environment-friendly bio-oil comprises the following components in part by weight: 50 to 70 parts of cyanobacteria extract oil, 2 to 4 parts of sodium cumenesulfonate, 5 to 10 parts of water, 15 to 25 parts of diesel oil, 2 to 6 parts of oleic acid, 2 to 6 parts of ethyl alcohol, 1 to 8 parts of modifier and 0.1 to 2 parts of cyclopentadienyl manganese tricarbonyl. The bio-oil disclosed by the invention can replace diesel and is high in heat value, energy-saving, environment-friendly, simple in preparation method, low in cost and easy for realizing engineering industrialization.

Description

technical field [0001] The invention relates to the field of chemical environmental protection, in particular to an environmentally friendly biofuel and a preparation method thereof. Background technique [0002] As an important petroleum refining product, diesel oil occupies a high share in the fuel structure of various countries. It is the main power fuel for many large vehicles (such as trucks, internal combustion engines and generators, etc.), and has the advantages of high power and low price. With the acceleration of dieselization of vehicles worldwide, the demand for diesel will increase in the future. The depletion of petroleum resources and the improvement of people's awareness of environmental protection have greatly promoted the development of diesel alternative fuels in countries around the world. [0003] There are also many problems in the application of diesel oil, such as low combustion efficiency, serious air pollution, a large amount of particulate dust, an...
