Adsorption and reactive process of gas and/or liquids in heterogeneous

systems and mathematical modeling and optimization of the related

processes are the activities of this laboratory. Some of the activities are

focused on formation of the fine layers, as core-shell catalysts, membrane

fabrication and modeling their properties.

The methods of testing adsorbents, related properties and membranes need

different equipments and facilities and this lab is working on set-up these

systems.

Synthesis and production of some nano-structured materials, nano-

particles, nano-films and nano-photocatalysts are taken place in this lab

and their properties are determined experimentally. The catalytic

properties as well as adsorptive properties of the produced materials are

investigated and modeled in heterogeneous systems.

Mathematical modeling, simulation and optimization of the adsorption

processes, heterogeneous reactors (fixed beds, trickle beds, moving beds,

bubble columns, fluidized, slurry, and membrane reactors) are performed

for refining natural gas and oil, environmental issues, CO2 fixation,

hydrogen purification, and production high-value products, in this lab.
