Abstract: ]The current manuscript investigates the technical feasibility for the production of advanced aviation and marine e-fuels from microbial lipids via hydrotreatment. Two microbial lipids produced from municipal solid wastes (spent coffee grounds and orange peels) using the selected oleaginous yeast of the L. starkey and C. curvatus were tested. Due to the limited microbial lipids availability, the free fatty acid composition (FFA) of the microbial lipids derived from each waste was analyzed, based on which various vegetable oils (palm, flaxseed, olive and pumpkin oil) were blended to formulated the two lipid feeds that match by 82 and 84 % the FFA profile to the original ones. The two simulated feedstocks were hydrotreated in a TRL3 plant targeting to optimize the conversion process via the investigation of various operating windows. The optimum operating window for the examined feeds was found at 330 °C, 83 bar pressure, 1 hr−1 LHSV and 840 NL/L hydrogen/oil ratio. Hydroprocessing of the simulated feedstocks was able to lead to diesel and jet range hydrocarbons that consists from N-paraffins up to 95 wt%. Upon the identification of the optimal operating window and feedstock, 10 L of total hydrotreated product was produced and fractionated rendering aviation, marine and road transport hydrocarbons. As the hydrogen for the hydrotreatment plant is produced via solar energy, the produced fuels are called electrified fuels ("e-fuels). The produced e-fuels were evaluated according to standard fuel specifications (Jet A1, DMA, EN 590), showing that good quality road transport, marine and aviation e-fuels can be produced via hydroprocessing of microbial lipids. [Display omitted] • E-fuels production via hydrotreatment of microbial lipids. • Microbial lipids from wastes of spent coffee grounds and orange peels. • Blend of vegetable oils can simulate the FFA composition of microbial lipids by 85 %. • Optimum operating window at 330 °C, 83 bar, 1hr−1 LHSV and 840 nl/l H2/oil ratio.
