Abstract

Pinane is a product derived from turpentine, a renewable resource that is highly valued. Due to its unique multicyclic ring structure, pinane has a relatively high energy density of 35.6 MJ L⁻¹, making it an excellent potential alternative to jet fuel. In this work, the low-temperature oxidation of pinane is comprehensively studied concerning the oxidative stability requirement of jet fuels. The apparent activation energy E_a and pre-exponential factor A of pinane oxidation are acquired according to the Kissinger method using a P-DSC apparatus as 97.6 ± 2.7 kJ mol⁻¹ and 5.3 ± 3.7 × 10¹⁰ min⁻¹, respectively, rendering it a relatively more oxygen-susceptible hydrocarbon compared to non-strained hydrocarbons. DFT calculations and experimental investigations have shown that the low-temperature oxidation of pinane begins with the hydrogen atom transfer (HAT) reaction and the rupture of the strained ring. Interestingly, although pinane can be easily oxidized, it shows very low deposition propensity in the JFTOT test, qualifying it as a potential jet fuel.

生物质喷气燃料蒎烷的低温热氧化†

Pinane是一种从松节油中提取的产品，松节油是一种非常有价值的可再生资源。由于其独特的多环结构，频烷具有35.6 MJ L−1的相对较高的能量密度，使其成为喷气燃料的绝佳潜在替代品。本工作针对喷气燃料对氧化稳定性的要求，对蒎烷的低温氧化进行了全面的研究。根据Kissinger方法，使用P-DSC装置获得了蒎烷氧化的表观活化能Ea和指数前因子A，分别为97.6±2.7kJ mol−1和5.3±3.7×1010min−1，使其与非应变烃相比是一种相对更易受氧影响的烃。DFT计算和实验研究表明，蒎烷的低温氧化始于氢原子转移（HAT）反应和应变环的断裂。有趣的是，尽管蒎烷很容易被氧化，但在JFTOT测试中，它显示出非常低的沉积倾向，使其成为一种潜在的喷气燃料。
