Embodiment Construction

[0059] The present invention will be described below with specific examples, but the protection scope of the present invention is not limited to these examples.

[0060] 1. Experiment of preparing hydroxycyclopentenone from furfuryl alcohol (influence of catalyst, tank reactor)

[0061] In a 100mL reactor, add 50mL of furfuryl alcohol aqueous solution with a mass concentration of 2%, add a certain amount of alkali catalyst, and react at a certain temperature for a specific time.

[0062] Table 1. Rearrangement activity of different base catalysts

[0063]

[0064] It can be seen from the results in Table 1 that different base catalysts can effectively catalyze the rearrangement reaction of furfuryl alcohol and obtain high yields of hydroxycyclopentenone, among which CeO 2 The effect is slightly worse. But even without adding any catalyst, a yield of 60% of hydroxycyclopentenone can still be obtained under better reaction conditions. The influence of the amount of catalys...

Abstract

The invention relates to a method for preparing JP-10 aircraft fuel from furfuryl alcohol. The method for preparing the JP-10 aircraft fuel from furfuryl alcohol comprises the following four reactions: reaction I, in the presence of base catalyst or in the absence of a catalyst, preparing hydroxyl cyclopentenone from a furfuryl alcohol solution through a rearrangement reaction; reaction II, performing a D-A reaction on the hydroxyl cyclopentenone and cyclopentadiene so as to generate a C10 oxygen-containing compound; reaction III, performing hydrodeoxygenation on the C10 oxygen-containing compound generated in the former step so as to obtainendo-tetrahydrodicyclotadiene; and reaction IV, isomerizing the endo-tetrahydrodicyclotadiene, thereby obtaining exo-tetrahydrodicyclopentadiene, wherein theexo-tetrahydrodicyclopentadiene can be directly used as the JP-10 aircraft fuel. The catalyst and the raw materials used in the method are cheap and easy to obtain and have relatively high activity and selectivity for rearrangement reactions of furfuryl alcohol, D-A reactions of hydroxyl cyclopentenone and hydrodeoxygenation. The invention provides a cheap and efficient synthesis method forsynthesizing JP-10 aircraft fuel from a lignocelluloses based platform compound, namely tfurfuryl alcohol.

Description

technical field [0001] The invention relates to a method for preparing JP-10 aviation fuel from furfuryl alcohol. It specifically includes four-step reactions: reaction one is to prepare hydroxycyclopentenone through rearrangement reaction of furfuryl alcohol solution under the condition of alkali catalyst or no catalyst; reaction two is to generate D-A reaction between hydroxycyclopentenone and cyclopentadiene C10 oxygenated compounds; Reaction 3 hydrodeoxygenates the C10 oxygenated compounds generated in the previous step to generate bridged tetrahydrodicyclopentadiene; Reaction 4 is the isomerization of bridged tetrahydrodicyclopentadiene to generate pendant tetrahydrodicyclopentadiene Diene, the obtained pendant tetrahydrodicyclopentadiene can be directly used as JP-10 aviation fuel. Compared with the currently reported method for preparing JP-10 aviation fuel, the raw material source of the present invention is the renewable biomass platform compound furfuryl alcohol, wh...
