In this short communication, vacuum residue, bitumen, and pyrolized fuel oil were analyzed using matrix-assisted laser desorption/ionization – time of flight (MALDI-TOF) analysis to investigate the molecular weight distribution (MWD) variation of heavy oil during visbreaking. The visbreaking of vacuum residue was carried out at 350°C, 400°C and 450°C. Vacuum residue products were studied based on...
Pitch synthesis from pyrolyzed fuel oil (PFO) was conducted to understand the empirical synthesis tendency as a function of reaction temperature. Additionally, the chemical and physical characteristics of PFO and produced pitch are identified using X-ray diffraction analysis, thermogravimetric analysis, softening point analysis, and matrix-assisted laser desorption/ionization-time of flight (MALDI-TOF)...
In this work, pitch was synthesized by a thermal reaction of pyrolyzed fuel oil (PFO), and its thermal properties were characterized using thermogravimetric and softening-point analyses. Thin-layer chromatography-flame ionization detection (TLC-FID) was performed to identify the saturated, aromatic, resin, and asphaltene (SARA) fractions to better understand the characteristics of the pitch produced...
