Abstract
Systems and methods for direct crude oil upgrading to hydrogen and chemicals including separating an inlet hydrocarbon stream into a light fraction and a heavy fraction comprising diesel boiling point temperature range material; producing from the light fraction syngas comprising H2 and CO; reacting the CO produced; producing from the heavy fraction and separating CO2, polymer grade ethylene, polymer grade propylene, C4 compounds, cracking products, light cycle oils, and heavy cycle oils; collecting and purifying the CO2 produced from the heavy fraction; processing the C4 compounds to produce olefinic oligomerate and paraffinic raffinate; separating the cracking products; oligomerizing a light cut naphtha stream; hydrotreating an aromatic stream; hydrocracking the light cycle oils to produce a monoaromatics product stream; gasifying the heavy cycle oils; reacting the CO produced from gasifying the heavy cycle oils; collecting and purifying the CO2; and processing and separating produced aromatic compounds into benzene and paraxylene.
