Problems solved by technology

Although it can also be used as engine fuel, its chemical composition and properties are obviously different from traditional fuels, and there are some shortcomings and problems in the use process, such as the molecule contains ester groups, its oxygen content is high, and its thermal stability is poor , the combustion calorific value is also low, and it will corrode the engine, etc. In the process of methyl esterification, due to the choice of inorganic acid or inorganic base as the catalyst, a large amount of waste liquid will inevitably be produced in the production process, and the transesterification process will also produce difficult to handle Glycerin, it can be seen that the quality of the oil prepared by this method is lower and the cost is higher

Embodiment 1

[0025] Use a buckwheat sheller to peel off the husk of the thousand-year-old tung seed to obtain the nuts. The content of the nuts in the shell residue is 0.6wt%, and the content of the shell residue in the nuts reaches 0.3wt%. A large amount of shell residue produced during the shelling process can be used for Preparation of chemical raw materials such as potassium carbonate, furfural and activated carbon. Put the nuts into the screw oil press and squeeze them into crude oil. The crude oil is squeezed and filtered through a filter to obtain rough millennium tung seed oil. The filtered kernel residue contains almost no oil. After further processing, the kernel residue can be made into vegetable oil. Casein, artificial petroleum, fillers for Bakelite plastics, animal feed, food additives and soil fertilizers.

Abstract

The present invention provides an oil, aviation bio-fuel component and a preparation method of aviation bio-fuel component by using Aleurites montana seeds. The method comprises the specific steps of: peeling the shells of Aleurites montana seeds to obtain kernels; squeezing the kernels to obtain crude oil; subjecting the crude oil to extrusion filtration and impurity removal to obtain refined oil; and subjecting the refined oil to catalytic hydrogenation and separation to obtain the main product of aviation bio-fuel component. The aviation biofuel component prepared by the present invention has composition and properties very similar to those of conventional jet fuel, is high in calorific value, environmentally friendly, renewable, and free of aromatics, olefins and sulfur. The raw materials are cheap and easy to get; the production process is simple, and by-products can be used effectively, so as to greatly reduce the production cost of aviation biofuel and is in favor of large-scale production.

Description

technical field [0001] The invention relates to the field of aviation biofuels, in particular to an oil product, aviation biofuel components and a method for preparing aviation biofuel components using millennium tung seeds. Background technique [0002] With the development of society and economy, fuel prices continue to rise, transportation costs continue to rise, and operating pressures are gradually increasing. Even as the world's largest air transport country, the United States, many of its airlines are due to factors such as rising fuel costs. loss or even bankruptcy. For the largest Brazilian domestic airline in China and Latin America, fuel costs account for about 40% of its operating costs. It can be seen that the continuous rise in aviation fuel prices has seriously eroded the profit margins of airlines in various countries and forced the global aviation industry. Must find ways to find new alternative energy sources. [0003] The European Union formulated and pr...
