Synthesis of bimetallic/carbon nanocomposite and its application for phenol removal
Published in Journal of the Iranian Chemical Society
AbstractThe research study goes through the development of Al/Mn impregnated multi-walled carbon nanotubes (MWCNTs) and its use in the adsorption of phenol from aqueous solution. The Al/Mn decorated CNTs (CAM) were characterized by different characterization techniques such as BET, XRD, SEM-EDX, TGA and Raman spectroscopy to study the porosity, min...
Solid support ionic liquid (SSIL) adsorbents for mercury removal from natural gas
Published in International Journal of Environmental Science and Technology
Mercury removal is an integral part of gas-processing and coal combustion plants due to its implication on health, environment and process equipment. Utilization of impregnated carbons and metal sulfide-based adsorbents for mercury removal are common, however with limitations in adsorption capacity and life time. Continued efforts to develop porous...
An experimental investigation on effective parameters of batch impregnation systems: a case study on Pt–Sn/Al2O3 catalys...
Published in Applied Petrochemical Research
The adsorption of hexachloroplatinic acid on Sn-impregnated γ-alumina support in the presence of the competitive chloride ion, as a step in preparation of multi-metallic Pt-based catalyst (such as Pt–Sn/Al2O3), was studied. The transient adsorption data were obtained by studying the impregnation of Sn/Al2O3 with H2PtCl6 in an external recycle packe...
Hydrogenolysis of lignin over Ru-based catalysts: The role of the ruthenium in a lignin fragmentation process
The catalytic performances of two different classes of catalysts containing nickel or/and ruthenium as the active sites were studied in the depolymerisation of lignin isolated from Miscanthus × giganteus. The catalysts were prepared either by coprecipitation (ie, (RuNiMgAlO)x, (RuNiAlO)x, (NiAlO)x, (NiMgAlO)x) or by wet impregnation (ie, Ru/Al2O3) ...

Optimization of the synthesis technique of molybdenum sulfide catalysts supported on titania for the hydrodesulfurizatio...
Published in Reaction Kinetics, Mechanisms and Catalysis
The present work deals with the optimization of the preparation method for the synthesis of unpromoted molybdenum catalysts supported on titania. Four methodologies have been followed: equilibrium–deposition–filtration (EDF), wet impregnation (WI), dry impregnation (DI) and controlled wet impregnation (CWI). The Mo surface density of all catalysts ...
Co-doping a metal (Cr, Mn, Fe, Co, Ni, Cu, and Zn) on Mn/ZSM-5 catalyst and its effect on the catalytic reduction of nit...
Published in Research on Chemical Intermediates
Selective catalytic reduction (SCR) of NOx by NH3 over a series of Mn–M/Z catalysts (M = Cr, Mn, Fe, Co, Ni, Cu, Zn, and Z = the ZSM-5 Zeolite) synthesized by wet impregnation method was investigated. Mn–Fe/Z, Mn–Co/Z, and Mn–Cu/Z catalysts exhibited approximately 100 % NOx conversion over a wide temperature range (200–360 °C) in a defined atmosphe...
Characteristics of Manganese Supported on Hydrous Titanium Oxide Catalysts for the Selective Catalytic Reduction of NOx ...
Published in Topics in Catalysis
Mn oxide supported on two different groups of titania, hydrous or crystalline titanium oxide, were investigated for the selective catalytic reduction of NOx with NH3 (NH3 SCR). Hydrous titania was prepared by hydrolysis of titanium tetraisopropoxide followed by drying, and crystalline titanium oxide was prepared with further calcination of the hydr...
Waste Animal Bone as Support for CaO Impregnation in Catalytic Biodiesel Production from Vegetable Oil
Published in Waste and Biomass Valorization
Heterogeneous catalyst plays a vital role in this process, especially in view of cost and reusability. In the present study, a useless material such as waste animal bone was employed as support for calcium oxide impregnation. CaO was impregnated on the pre-treated waste sheep bone as an active component in different loading levels. The catalyst was...
