This paper presents an economic pathway for high energy density fuels production from lignin-derived intermediates and refinery waste gas streams. The lignin-derived intermediates, including toluene and xylenes, are obtained from one-pot lignin conversion catalyzed by metal(s)-zeolite Y catalysts with the presence of hydrogen in water at 250°C [1-2]. Alkylation of the intermediates with refinery waste gas streams, which contain up to 10% olefins, and subsequent distillation, produces C8-C12 hydrocarbons with high octane number (>120) and energy density using the existing refinery infrastructure. The octane numbers and energy density of the components are summarized. Brief economic analysis is provided.
