Chemical speciation of petroleum and bio-oil coprocessing products: Investigating the introduction of renewable molecules in refining processes

摘要: Abstract The pentane solvent deasphalting (SDA) process was carried out with petroleum vacuum residue (VR) blend a bio-oil (BO) and solely the as raw material. Two fractions each were produced: deasphalted oil (DAO) asphaltic (AR). This study deals chemical speciation of investigation insertion renewable molecules in VR. Chemical characterization performed by two high-resolution techniques: GC × GC-TOFMS ESI(±)-Orbitrap HRMS. data showed that all are mixtures hydrocarbons heteroatomic midpolar to polar compounds containing wide variety functions. Aliphatic detected only DAO fractions, showing SDA process, extraction these constituents VR not affected inclusion. HRMS results allowed for identification nitrogen, oxygen, sulfur, mixed classes. obtained use both techniques evaluation effect on assisted degree making them attractive application refining processes, such catalytic cracking. from material inserted bench-scale cracking load obtaining satisfactory results, AR fraction introduced an asphalt cement additive promising achieved aging tests.
