Deep Hydrotreatment of Middle Distillates Obtained by Pyrolysis of Oil Shale and Oil Sands Bitumen

Catalytic Hydrotreatment of Light Distillates Obtained from Bio-Oil for Use in Oxygenated Liquid Fuels

Bio-oil can be fractionated into three parts according to their boiling points. This research reported that light distillates could be converted into oxygenated liquid fuels through a two-stage hydrotreatment approach, using a Pd/C catalyst. The main goal of the first hydrotreatment stage was to stabilize the high active components, which contained carbon–carbon double bonds and aldehyde groups...

The Presence of Polycyclic Aromatic Hydrocarbons (pah) in Oil Obtained at Pyrolysis of Jordan Oil Shale

The presence of polycyclic aromatic hydrocarbons (PAH) in the oil obtained at pyrolysis of Jordan oil shale in a fluidised-bed reactor in the atmosphere of nitrogen and nitrogen/steam has been investigated. The final pyrolysis temperature was 520 °C, at which the maximum oil yield was established. The derived oils were fractionated into chemical classes using mini-column liquid chromatography f...

Vaporization Parameters of Primary Pyrolysis Oil from Kukersite Oil Shale

The objective of this study was to obtain vapor pressure and heat of vaporization values of the less volatile heavy end of the Kukersite oil shale primary pyrolysis oil and therefore to have a quantitative insight into the vaporization ability of the oil during the pyrolysis process. The shale oil was produced via rapid pyrolysis in a laboratory scale reactor and collected in a solvent filled c...
