TG-DSC and TG-FTIR analysis of heavy fuel oil and vacuum residual oil pyrolysis and combustion: characterization, kinetics, and evolved gas analysis

Interactions in co-pyrolysis of Salicornia bigelovii and heavy fuel oil

“…Heavy hydrocarbons, such as aromatics, resins and asphaltenes, in HFO decompose at higher temperatures between 300–500 °C, as observed in the DTG profile. Similar peaks were observed by Abdul Jameel et al 31 and Alabbad et al 39 for HFO pyrolysis. In biomass, the first decomposition region in the DTG profile is attributed to moisture loss.…”

“…Also, reactions such as homolytic bond fission and hydrogen abstraction creating radicals that then undergo β-scission producing unsaturated hydrocarbons or radical addition to generate long chain radicals and finally radical termination via recombination creating longer chains occur. 39 These reactions result in compounds such as aliphatic hydrocarbons, naphthalene and benzothiophene derivatives.

“…The SARA (Saturates, Aromatics, Resins, and Asphaltenes) of the HFO used is also available in Table 1. 39…”

On the Products from the Pyrolysis of Heavy Fuel and Vacuum Residue Oil

“…Jameel et al [25] investigated the functional groups evolving from the pyrolysis and combustion of HFO using a TG-FTIR to understand the formation of pollutants. In a recent study by AlAbbad et al [26], apparent kinetics, pyrolysis and combustion parameters and time evolution of functional groups was studied via means of a TGA couple to instruments such as FTIR and differential scanning calorimetry. To identify the primary pyrolysis products, fast pyrolysis of VRO was performed in a Pyroprobe®-gas chromatography/MS (GC/MS) in the temperature range 650-850 °C and investigated heating range was in the range 500-20000 °C s -1 [27].…”
