Breen et al  and Seo et al  analyzed the liquid products obtained from the catalytic degradation of HDPE using GC-MS and found that the products were mainly consisted of paraffins, olefins, naphthenes
and aromatics (PONA) where the detailed composition of the products has not been mentioned.
, alkynes, aromatics, and others), from viscously
Hydrotreatment is a process that converts polycyclic aromatics into naphthenes
and allows for production of environmentally-sound naphthenic oils without production of carcinogenic side products.
Hydrogenating all of the aromatics present in bitumen will not solve this problem because the resulting naphthenes
are still not suitable for the FCC process.
Toxicity is greatest with the aromatic hydrocarbons followed by the naphthenes
and least with the paraffins(11).
researchers, Mumbai, India, have patented a process for oligomerization of olefins contained in refinery distillate streams including paraffins, naphthenes
A method is presented which utilizes lumped composition data (Paraffins, Isoparaffins, Aromatics, Naphthenes
, and Olefins--PIANO) to calculate generalized distances between samples in a five-dimensional PIANO space.
A calibration curve was assayed using the 78 compounds from the detailed hydrocarbon analysis (DHA) Paraffins, Isoparaffins, Olefins, Naphthenes
, and Aromatics (PIONA) standard (Restek Cat.
Real-Time Analyzer's Portable Fuel Quality Analyzer (PFQA) determines physical and chemical properties for diesel, gasoline and jet fuels in 10 sec, including but not limited to cetane index, cloud point, distillation values, flash point, freezing point, pour point and viscosity; as well as aromatics, ethanol, MTBE, naphthenes
, saturates and sulfur.
