Grindelia squarrosa biocrude is a promising feedstock for producing high-density cycloalkane fuels for high-performance aircraft due to the branched tricyclic nature of its primary diterpenoid component, grindelic acid. Herein we designed a novel biphasic tandem catalytic process (biTCP) for the conversion of Grindelia squarrosa biocrude into high-density aviation fuels with a superior carbon atom efficiency. The systematic experimental studies provided valuable insights into the effects of process conditions. The detailed speciation was carried out with the complementary chemical analysis techniques. Under the optimum conditions, a ∼90% carbon yield of aviation fuel components was produced from the Grindelia squarrosa biocrude. Multistep tandem reactions, including cyclic ether ring opening, dehydration, hydrogenation, and decarboxylation were carried out in the “one-pot” biTCP. The detailed catalytic reaction mechanism is discussed. A continuous process was designed integrating the extraction of biocrude and its conversion to dense jet fuels using biTCP. The techno-economic analysis has been performed, and in its current state, the proposed process is expected to deliver price-competitive high-density aviation fuel products.

利用干旱土地作物生产高密度可再生航空燃料

Grindelia squarrosa biocrude是一种有前途的原料,由于其主要的二萜类成分即草酸,其支链三环性质可用于生产高性能飞机的高密度环烷烃燃料。在本文中,我们设计了一种新颖的双相串联催化工艺(biTCP),用于将格林德里亚(Brindelia squarrosa)生物粗品转化为具有出色碳原子效率的高密度航空燃料。系统的实验研究为过程条件的影响提供了宝贵的见解。使用辅助化学分析技术进行了详细的物种形成。在最佳条件下,Grindelia squarrosa可产生约90%的航空燃料成分碳产率。生物粗暴。多步串联反应,包括环醚开环,脱水,氢化和脱羧,均在“一锅” biTCP中进行。讨论了详细的催化反应机理。设计了一个连续过程,该过程结合了使用biTCP将生物原油的提取以及其转化为高密度喷气燃料的过程。已经进行了技术经济分析,在目前状态下,拟议的过程有望交付具有价格竞争力的高密度航空燃料产品。
