Characterization and upgradation of crude tire pyrolysis oil (CTPO) obtained from a rotating autoclave reactor

Liquid fuel from waste tires: novel refining, advanced characterization and utilization in engines with ethyl levulinate as an additive

“…We had reported the laboratory-scale upgrading of CTPO by stirring a diluted solution of CTPO in petroleum ether with silica gel on a magnetic stirrer (magnetic-stirring method). 15,16 When scaling up the laboratory-scale batch process, additional features were incorporated, such as a micro-ltration apparatus, an overhead stirrer, and chiller. The recovery of upgraded oil (i.e., StTPO) was noticeably higher (ca.…”

Chemical characterization of waste tire pyrolysis products

“…Besides, NMR has a good technique to find aromatic and aliphatic hydrogen and carbon atoms in fuel sample. The resonance peaks area were characterized by the amount of 1 H or 13 C atoms related with chemical compositions at spectra [31]. The qualitative composition of WTO, DLF, GLF, DF and GF were determined in terms of highresolution technique.…”

“…Besides, the liquid has disgusting odor, low power of hydrogen (pH), low heating value and high sulfur amount which causes air pollution, high corrosion in engine with less burning capacity. Due to tire oil problems, it was treated with catalyst to improve properties of oil for burning [11][12][13][14].…”

“…Furthermore, Ground Tire Rubber (GTR) and Reclaim Rubber (RR) were converted at 400-600 o C. The alkanes/aromatic ratios of FT-IR results and elemental analyses were close to each other. 1 H-NMR and 13 C-NMR spectra were declared at different concentrations of aromatics, and they exhibited similarities due to each property. Lopez et al [17] investigated natural and synthetic rubber of WTs conversion in conical spouted bed reactor between 425-600 o C. The liquid was tested by gas chromatography and mass spectrometry (GC-MS), two-dimensional gas chromatography (GCxGC) with distillation and elemental tests.…”

Sustainable Nanoplasmon‐Enhanced Photoredox Reactions: Synthesis, Characterization, and Applications

“…Out of which, pyrolysis process is a promising thermal depolymerization approach, which involves heating of the biomass or polymer such as worn tire or plastics at a temperature of 400–600 °C yield oil, gas and carbon black. [ 196 ] Low calorific value, high acidity, pungent smell, high viscosity, inferior storage stability, low flash point are the major problems facing in most of tire pyrolysis plants. The major limitation of pyrolysis processes is uneven distribution of heat across the reactor, which results in inferior oil quality with very low yield.…”
