Promoting Research Work

All relevant results will be published in international journals and presented at national and international conferences. In addition, if these materials perform well, the patentability of any new results will be considered before any public disclosure.

Training Details

Description

Textural and chemical characterization of the samples will be carried out by different techniques, and their behavior as adsorbents will be assessed in NDU.

Objectives

  • Synthesis of ACs from distillation residues by different activation methods
  • For chemical activation: KOH in a residue: ratio of 1:1 and T = 800 °C.
  • For physical activation: excess of CO2 and T = 800 °C.
  • For hydrothermal activation: a high-pressure reactor will be used at different temperatures (180, 190, 200 °C) and times (4, 8, 12 h). A carbonization/activation step could be needed.

    Textural and chemical characterization by physical adsorption of nitrogen, SEM, FTIR, TG/DTG, and measurements of the point of zero charges.
