Mathematical modeling and parameters optimization of acrylonitrile degradation in biofilters

Hajar seyfi; Sirous shafiei; Reza Dehghanzadeh; Parya Amirabedi

Volume 18, Issue 3 , December 2021


  Removal of Acrylonitrile (AN) from waste gas streams using biological methods has recently gained more attraction due to their better performance. The purpose of this research is modeling of the AN removal by a bio-filter. The model validation is done using the experimental data of a bench-scale bio-filter ...  Read More

CFD modeling and industrial evaluation of a cyclone cascade for HDPE catalyst production

Saeed Ovaysi

Volume 18, Issue 3 , December 2021


  A new approach is proposed to evaluate various designs for gas-solid cyclone separators. This approach uses single-phase flow simulation results to find a quantitative measure of flow symmetry in a given cyclone. Flow symmetry is computed by averaging imbalances of non-axial velocities throughout the ...  Read More

Adsorption optimization of Pb(II) and Zn(II) onto the EDTA-modified MnO2/Chitosan/Fe3O4 nanocomposite from aqueous solution using RSM according to CCD method

Adel Panahadeh; Arsalan Parvareh; Mostafa Moraveji

Volume 18, Issue 3 , December 2021


  Central composite design (CCD) was employed to investigate the adsorption of Pb(II) and Zn(II) metal ions as well as methylene blue (MB) as an aromatic anion by a new EDTA/MnO2/CS/Fe3O4 synthesized nanocomposite. The effect of possible affective factors including contaminant concentration (20-200 mg/L), ...  Read More

Investigation on Ni-Co bimetallic supported catalysts on dry reforming of methane

Gholamreza Moradi; hamed Hemmati; sahar rostami

Volume 18, Issue 3 , December 2021


  In this work, the effect of Si/Al ratio on the bimetallic (Ni-Co) zeolite supported catalysts on Dry Reforming of Methane (DRM) has been studied. Samples are prepared with impregnation and sol-gel method and then calcined at 550℃ for 2hrs. The catalysts were characterized by XRD, XRF, FESEM, BET and ...  Read More

Phosphate removal from aqueous environment using iron oxide/activated carbon composite: Ziziphus nuts derived activated carbon as a new precursor

behnam mousazadeh; nima . mohammadi; touba hamoule

Volume 18, Issue 3 , December 2021


  Ziziphus nuts are abundant in Khuzestan province, Iran, and are considered as an unwanted natural biomass waste. The present study aimed to develop low-cost activated carbon from Ziziphus nuts as a new precursor for phosphate removal from the water environment. Iron oxide modification was performed to ...  Read More
