Bio-Oil Production by Thermal Cracking in the Presence of Hydrogen

‏‎suppression of coke formation in thermal cracking by coke inhibitors‎‏

‏‎the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...

A Pilot Study of Syngas Production from Bio-oil Thermal Cracking in a Bubbling Fluidized Bed Reactor

A fluidized bed reactor that is operating in the bubbling regime has been developed for the conversion of bio-oils to syngas.The reactor consists of a 7.6 cm I.D. (or internal diameter) bed, with an expanded freeboard. The volume of the reactor can be adjusted to vary the gas residence time. This reactor has been used to carry out either thermal or catalytic cracking for reforming bio-oils.A ga...

Sulfur distribution in the oil fractions obtained by thermal cracking of Jordanian El-Lajjun oil Shale

The extracted shale oil by the thermal cracking process of the El-Lujjan oil shale showed that the yield of oil was around 12 wt%. The amount of sulfur in this shale oil was found to increase (from 7 to 9.5 wt%) with the increase of the boiling point for different distillate fractions. Sulfur in Jordanian oil shale was found to be mainly organic sulfur with negligible amounts of inorganic sulfu...
