Abstract

The invention discloses a method for preparing biological aviation fuel by using litsea cubeba kernel oil, comprising the following steps of: (1) refining the litsea cubeba kernel oil; (2) introducing the refined litsea cubeba kernel oil into a fixed-bed hydrogenation reaction device and sequentially carrying out hydrogenation and deoxygenation reaction and isomerization reaction; (3) collecting liquid-phase components through a condenser; (4) distilling and collecting distillate with the temperature of 150-280 DEG C; and (5) refining the collected distillate through a fiber liquid membrane-composite adsorption unifying device and a dielectric field refining device to obtain the biological aviation fuel meeting the aviation fuel specification. By using the method, the obtained biological aviation fuel contains no sulfur and arene and is good in quality, high in cleanliness 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 litsea cubeba fruit stone oil. Background technique [0002] At present, all countries in the world are facing the dual challenges of energy crisis and climate change. With the depletion of fossil energy, biofuels have gradually entered the field of vision of mankind. Because traditional resources such as coal, oil, and natural gas burn the carbon fixed in the interior of the earth and emit it into the atmosphere, their utilization will inevitably increase the content of carbon dioxide in the atmosphere, thereby intensifying the greenhouse effect of the earth. The formation of biomass is the process by which plants convert carbon dioxide already present in the atmosphere into glucose and then into plants through the photosynthesis of chlorophyll. This process can effectively reduce the carbon dioxide content in the a...
