Embodiment 1

[0030] This embodiment includes the following steps:

[0031] (1) Filter the eucalyptus oil to remove particulate impurities, add softened water at the same temperature after heating to 70°C (the weight of the added demineralized water is 3% of the weight of the eucalyptus oil), stir for 30 minutes, and then use 3000r Centrifuge at a speed of 1 / min for 30 minutes, take the supernatant, and dry it in a vacuum oven at 103°C for 3 hours to obtain refined eucalyptus oil;

[0032] (2) After cooling the refined eucalyptus oil obtained in step (1), it is introduced into a fixed-bed hydrogenation reaction device filled with a hydrodeoxygenation catalyst to perform a hydrodeoxygenation reaction; the hydrodeoxygenation catalyst is NiO-MoO 3 / γ-Al 2 o 3 Catalyst, the amount of which is equivalent to 3% of the weight of the obtained refined eucalyptus oil, the temperature is raised to 400°C, the absolute pressure is 4MPa, and hydrogen is introduced at the same time, the hydrogen-oil vol...

Embodiment 2

[0038] This embodiment includes the following steps:

[0039] (1) Filter the eucalyptus oil to remove small particle impurities, heat to 70°C, then add demineralized water at the same temperature (the weight of demineralized water added is 3% of the oil weight), stir for 30 minutes, and then use 3000r / Centrifuge at a speed of 1 min for 30 minutes, take the supernatant, and dry it in a vacuum oven at 103°C for 3 hours to obtain refined eucalyptus oil;

[0040] (2) After cooling the refined eucalyptus oil obtained in step (1), it is introduced into a fixed-bed hydrogenation reaction device filled with a hydrodeoxygenation catalyst to carry out a hydrodeoxygenation reaction; the hydrodeoxygenation catalyst is CoO-MoO 3 / γ-Al 2 o 3 Catalyst, the amount of which is equivalent to 2% of the weight of the obtained refined eucalyptus oil, the temperature is raised to 380 ° C, the absolute pressure is 5 MPa, and hydrogen is introduced at the same time, the volume ratio of hydrogen to...

Embodiment 3

[0044] This embodiment includes the following steps:

[0045] (1) Filter the eucalyptus oil to remove small particle impurities, heat to 70°C, then add demineralized water at the same temperature (the weight of demineralized water added is 3% of the oil weight), stir for 30 minutes, and then use 3000r / Centrifuge at a speed of 1 min for 30 minutes, take the supernatant, and dry it in a vacuum oven at 103°C for 3 hours to obtain refined eucalyptus oil;

[0046] (2) After cooling the refined eucalyptus oil obtained in step (1), it is introduced into a fixed-bed hydrogenation reaction device filled with a hydrodeoxygenation catalyst to perform a hydrodeoxygenation reaction; the hydrodeoxygenation catalyst is NiO-WO 3 / ZSM-5 catalyst, the amount of which is equivalent to 5% of the weight of the obtained refined eucalyptus oil, the temperature is raised to 400°C, the absolute pressure is 3.5MPa, and hydrogen is introduced at the same time, the volume ratio of hydrogen to oil is 900...

Abstract

A method for preparing biological aviation fuel by utilizing cornus wilsoniana oil comprises the following steps of: filtering and decontaminating the cornus wilsoniana oil, adding softened water with equal temperature at 60-70 DEG C, stirring, centrifugating, taking supernatant, and drying; introducing the refined cornus wilsoniana oil into a stationary bed hydrogenation reaction device, conducting hydrodeoxygenation reaction and somerization reaction to obtain a gas-liquid mixture; condensing the gas-liquid mixture by a condenser, and collecting liquid phase product; distilling the liquid phase product, and collecting fraction between the 150-280 DEG C; introducing the fraction collected in the step (4) into an oil refinement device for high-cleanness refinement, thus obtaining the biological aviation fuel. With the adoption of the method, the obtained biological aviation fuel does not contain sulfur or aromatic hydrocarbon, and is good in quality, high in cleanness, and environment-friendly.

Description

technical field [0001] The invention relates to a method for preparing bio-aviation fuel, in particular to a method for preparing bio-aviation fuel by utilizing eucalyptus oil. Background technique [0002] Fossil fuels are currently the main energy source for human production and life. Petroleum, coal, natural gas and other non-renewable fossil fuels account for 86.8% of energy consumption. According to the current consumption rate of fossil fuels in the world, these energy sources can only be used by human beings for about 45 to 50 years. Natural gas is 50-60 years old, and coal is 200-220 years old. Therefore, the energy crisis has become the main problem facing human development. [0003] As an alternative energy source, bioenergy has received extensive attention. So far, the development of biofuels has gone through three stages: the first generation of biofuels mainly uses food crops and oil crops such as corn, sugarcane, soybean and castor as raw materials, because o...
