Embodiment approach

[0029] The preparation method of the aviation fuel additive involved in the second aspect of the present invention is to prepare the aviation fuel additive through condensation reaction and hydrodeoxygenation treatment sequentially from the feed liquid containing acetone, butanol and optional ethanol. According to some embodiments of the present invention, the preparation method of the aviation fuel additive comprises:

[0030] Step M, the ABE raw material liquid is carried out condensation reaction, makes C 8 -C 16 ketone / alcohol liquid mixture;

[0031] Step N, put C 8 -C 16 The ketone / alcohol liquid mixture is subjected to hydrodeoxygenation treatment, only one molecule of water is removed, and the carbon number remains unchanged, and an aviation fuel additive is obtained;

[0032] Wherein, the main component of the aviation fuel additive is C 8 -C 16 of paraffins. In some embodiments of the present invention, for example, the C 8 -C 16 paraffins including C 8 -C ...

Embodiment 1

[0089] (1) The ABE (ethanol: acetone: butanol=1:2.3:3.7) fermented liquid that 200g water content is 5wt% is placed in the 20mL tank reactor, is 1Cu-20ZrO in 2g composition 2 / 80SiO 2 In the presence of a solid catalyst, after a condensation reaction at 220°C for 15 hours, C was obtained by solid-liquid separation. 8 -C 16 ketone / alcohol liquid mixture. After detection and calculation, the transformation rate of ABE is 85%, and the C 8 -C 16 The ketone / alcohol selectivity was 68%.

[0090] (2) put C 8 -C 16 100g of the ketone / alcohol liquid mixture is placed in a fixed bed reactor, at 300°C and 5h -1 At a space velocity of 0.5% Pt / Al at a mole fraction of Pt 2 o 3 The aviation fuel additive (C 8 -C 16 alkanes). After detection and calculation, C 8 -C 16 99% conversion of ketones / alcohols, C 8 -C 16 The selectivity to paraffins was 85%. The results are shown in Table 1 and Table 2.

Embodiment 2

[0092] The difference between embodiment 2 and embodiment 1 is that the catalyst used for the condensation reaction is 1Ni-50MgO / 50SiO 2 , the water content in the ABE fermentation broth was 0, the amount of the hydrodeoxygenation catalyst was 0.5 g, and the rest of the reaction conditions were the same as in Example 1. The results are shown in Table 1 and Table 2.

Abstract

The invention relates to an aviation fuel additive and a preparation method and application thereof. The method comprises the step that the aviation fuel additive is prepared by taking material liquid or fermentation liquid which is obtained by means of fermentation of non-grain biomass and contains acetone, butanol and optional ethanol through a condensation reaction and hydrodeoxygenation treatment. The aviation fuel additive is C8-C16 alkane and does not contain arene, and the mass content of carbon and hydrogen is larger than 98 wt%; the aviation fuel additive can be compounded with aviation fuel to be prepared into aviation alternative fuel, the aviation fuel standard is met, and meanwhile consumption of petroleum-based aviation fuel can be greatly reduced. According to the preparation method of the aviation fuel additive, the production technology is simple, the product quality is good, the yield is high, the raw materials are wide in source, the production cost is low, and large-scale production can be achieved.

Description

technical field [0001] The invention belongs to the field of new energy, and relates to an aviation fuel additive and its preparation method and application. Background technique [0002] Aviation kerosene (abbreviated as aviation kerosene) is the fuel for aviation turbine engines and is composed of hydrocarbon compounds of different fractions. Including paraffins, naphthenes and aromatics, the typical carbon number range is 8-16. Jet kerosene is a type of fuel specially used in aircraft. It is of higher quality than fuel used in heating systems and cars. It usually contains different additives to reduce the risk of freezing and explosion due to high temperature. With the gradual depletion of human fossil energy, it is imperative to find new renewable energy to maintain human survival and sustainable social development. Bio-aviation kerosene can be produced from a variety of animal and vegetable oils by hydrogenation technology, catalyst system and process technology. For ...
