Abstract: The search for new alternative sources of raw materials for fuel production, including high-quality jet fuels, has been driven by the need to reduce greenhouse gas emissions. Bio-oil, a dark viscous liquid produced through fast pyrolysis of variety of raw materials, is a promising source for the production of fuels with a reduced carbon footprint. However, its composition, which includes about 25-40% water, makes its processing by classical methods much more complicated. This paper examines the co-processing of bio-oil (up to 40% by weight) and vacuum residue (up to 100% by weight) in a delayed coking unit. It demonstrates the effect of the proportion of bio-oil on the yield and quality of coking products. The study also investigates the influence of the main coking factors on product yield. Co-processing can expand the raw material pool and can be implemented at refineries without significant capital costs.
