The transition to a circular bioeconomy requires the development of sustainable processes for converting biomass into value-added chemicals, offering a renewable alternative to fossil resources and reducing greenhouse gas emissions. This study presents a novel, integrated catalytic pathway for the production of carbonaceous materials and gasoline-range hydrocarbons from biomass. The process sequentially combines biomass pyrolysis, co-hydrotreating of the resulting bio-oil (10 wt% blend with straight-run diesel fraction), and final catalytic cracking. A key innovation involved the development of a continuous-flow reactor system equipped with dual pumps to enable the simultaneous hydroprocessing of the immiscible bio-oil and diesel streams. Through systematic optimization, mild operational conditions (280–360 °C, 50  bar H2) were identified for each stage, culminating in a 53 wt% yield of gasoline-range hydrocarbons and a feedstock conversion of 81–84 wt%. This work demonstrates a viable and efficient strategy for integrating biomass valorization into conventional refinery infrastructure
