In view of the above, a process has been developed for co-conversion of biomass pyrolysis oil in refinery Delayed Coker unit (DCU) to produce sustainable low carbon fuels. Biomass pyrolysis oil is characterized by its unique features like high Conradson Carbon Residue content akin to heavy petroleum residues, processed in DCU. Bio-oil derived from fast pyrolysis of lignocellulosic biomass is a complex mixture of oxygenated compounds, which poses challenge for refinery processing. To evaluate the impact of bio-oil in varying proportion in conventional DCU feedstock, experimental study was undertaken using lignocellulosic biomass such as Jatropha, Karanjia, Rice straw & Wood based biomass pyrolysis oil in Batch Coker Unit and validated in 1 bbl/day DCU pilot plant unit. The experimental results indicate that inclusion of bio-oil in feed to DCU has several benefits including potential to reduce the coke yield & improve the yield of distillates. It was also observed that Bio-oil dosing in DCU feedstock depends on the quality of Bio-oil derived from biomass sources.
This paper describes development of a process for co-conversion of bio-oil in Delayed Coker unit for sustainable low carbon fuel production from waste biomass pyrolysis oil aiming towards âPath to Net Zeroâ.
