新型高密度燃料具有体积热值高，密度大，低温性质好等优点，在航空航天领域具有广泛的应用价值。本文对四氢三环戊二烯的异构化反应进行了研究，以进一步改善燃料的低温性质，满足高密度燃料使用中对低温性质的要求。

以三氟甲磺酸为催化剂，在无溶剂的条件下对四氢三环戊二烯进行异构化反应。系统的考察了催化剂用量，反应温度对该反应的影响。最佳反应条件为：催化剂用量8.5%，温度60℃。催化剂用量过多，或者温度过高导致结焦严重。

采用三因素三水平正交试验设计，考察了反应温度，催化剂用量，原料溶剂比三因素对四氢三环戊二烯异构化反应转化率的影响。极差分析表明大部分复配燃料的倾点低于-60℃，具有良好的低温性质。

本研究为以后的研究和燃料未来的实际应用提供了参考和数据支持。

New volume of high-density fuel with high calorific value, density, low temperature and good nature, in the field of aerospace has a broad application value. In this paper, three-tetrahydro cyclopentadiene isomerization reaction was studied in order to further improve low temperature properties of fuels to meet the high-density low-temperature fuel use in the nature of the request.

To trifluoroacetic acid as a catalyst, in solvent-free under the condition of the THC for three cyclopentadiene isomerization. Systems studied the amount of catalyst, reaction temperature of the reaction. The optimum reaction conditions are as follows: the amount of catalyst 8.5%, temperature 60 ℃. Excessive amount of catalyst, the temperature is too high or lead to severe coking.

Three-factor three-level orthogonal experimental design to study the reaction temperature, amount of catalyst, solvent materials tetrahydro three factors on the three cyclopentadiene isomerization conversion rates. Analysis showed that the majority of very poor fuel mixtures pour point lower than -60 ℃, with good low temperature properties.

The purpose of this study for future research and practical application of fuel future reference and data support.
