AI Technical Summary
Existing processes for converting renewable olefins into distillate fuels, such as jet fuel, face challenges in efficiently managing the exothermic nature of olefin oligomerization and achieving high energy density suitable for jet engines, which cannot be easily replaced by electric motor systems.
A two-stage oligomerization process using specific catalysts, including zeolite and amorphous silica-alumina, to convert ethylene and propylene into higher olefins, followed by hydrogenation to produce jet fuel range hydrocarbons, with heat management through staged olefin streams and dilution.
The process effectively converts olefins into jet fuel range hydrocarbons with high efficiency and energy density, addressing the exothermic challenges and meeting the demands of jet engines.
