The research aims to develop a novel approach for generating bio-jet fuel from palm oil and limonene without the need for external hydrogen, addressing the challenges faced by the aviation industry in seeking sustainable fuel sources. The study proposes a "carbon-chain filling strategy" (CFS) that utilizes a one-pot process to convert C10 terpene and lipids into jet fuel-ranged hydrocarbons, including aromatic hydrocarbons, without external hydrogen. The process involves the use of limonene as a C10 terpene, which releases aromatic hydrocarbons and hydrogen, and a PdNi/HZSM-5 catalyst to facilitate the conversion of palm oil to C14-C18 alkanes through hydrodeoxygenation. The in-situ generated hydrogen from limonene dehydroaromatization enables the hydrodeoxygenation of lipids, and the resulting hydrocarbon mixture resembles the composition and properties of commercial bio-jet fuel. The study concludes that this integrated process is a simple, efficient, and green method for producing bio-jet fuel, offering a high yield and addressing the high-demand issues for hydrogen, aromatics, and light alkanes in a single-step process.
