Pyrolysis of Oils from Unconventional Resources

open access: yesEnergies, 2023
In this study, oils from various sources were subjected to pyrolysis conditions; that is, without oxidizer, as the samples were heated to 500 °C, and held at that temperature.

The Use of Activated and Non-Activated Tar Sands as Adsorbents for Copper Ion Removal

open access: yesAdsorption Science & Technology, 2004
Jordanian tar sands were used as an adsorbent for the removal of copper ions from aqueous solutions. Experimental results showed that the adsorption of Cu 2+ ions onto tar sands was pH- and temperature-dependent.
