[0065]
[0066] 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 hydro...

Abstract
The invention relates to a method for preparing JP-10 aviation fuel from furfuryl alcohol. The method for preparing the JP-10 aviation fuel by adopting the furfuryl alcohol as a raw material comprises the following five steps: step I, enabling a furfuryl alcohol solution to have a rearrangement reaction to prepare hydroxylcyclopentenone under the condition of an alkaline catalyst or no catalyst; step II, enabling the hydroxylcyclopentenone to react with hydrogen under the catalysis of a hydrogenation catalyst to prepare 1,3-cyclopentanediol; step III, preparing cyclopentadiene or dicyclopentadiene by dehydrating the 1,3-cyclopentanediol; step IV, enabling the cyclopentadiene and the dicyclopentadiene to have an isomerization reaction to generate hanging dicyclopentadiene; and step V, hydrogenating the hanging dicyclopentadiene to generate hanging tetrahydro-dicyclopentadiene, and then rectifying and purifying to obtain the JP-10 aviation fuel. Raw materials used in the method are cheap and easy to obtain, the preparation process is simple, and the activity and selectivity for the rearrangement reaction of the furfuryl alcohol, the hydrogenation reaction of the hydrocyclopentenone and the dehydration reaction is relatively high. The invention provides a synthetic method with low cost and high efficiency for synthesizing the cyclopentadiene or the dicyclopentadiene from lignocelluloses-based platform compound and furfuryl alcohol.
Description
technical field [0001] The invention relates to a method for preparing JP-10 aviation fuel from furfuryl alcohol. It specifically includes five-step reactions: the first step is to prepare hydroxycyclopentenone through rearrangement reaction of furfuryl alcohol solution under the condition of alkali catalyst or no catalyst; the second step is to react hydroxycyclopentenone with hydrogenation catalyst Hydrogen reaction to prepare 1,3-cyclopentadiol; the third step is to prepare cyclopentadiene or dicyclopentadiene from 1,3-cyclopentadiol under the catalysis of acid catalyst; the fourth step is to prepare cyclopentadiene and dicyclopentadiene Dicyclopentadiene undergoes isomerization reaction to produce hanging dicyclopentadiene; the fifth step is hydrogenation of hanging dicyclopentadiene to produce hanging tetrahydrodicyclopentadiene, and then purified by distillation to obtain JP-10 aviation fuel. Compared with the currently reported method for preparing JP-10 aviation fuel...
