Currently, the global aviation industry is focusing on the development of alternative fuel components for aircraft engines that reduce greenhouse gas emissions from the life cycle emissions. Of particular interest is the integration of bio-based materials processing technologies into existing oil refining facilities. This research aims to explore coprocessing of pretreated lignocellulosic feedstocks using pyrolysis and coke-making processes and conventional feed via hydrocracking. Optimal operating conditions were determined, and the products of hydrocracking of various coking biogasoils were investigated. A kerosene fraction with a yield exceeding 25% by mass, resulting from combined hydrocracking, has been obtained, meeting most critical of the specifications for jet fuel as outlined in regulatory standards. © 2025 Elsevier B.V., All rights reserved.
