The search for strategies that contribute to circular economy, based on the valorization of by-products most diverse industries and processes, is one main environmental objectives at present. This study aims evaluate possibility valorizing from gasification carbonization polymeric residues biomass natural origin through their application in adsorption processes. selected carbon resulting thermo...

In this study, green or eco-friendly synthesis of TiO2 nanoparticles (NPs) was performed by using the aqueous extract of Acanthophyllum laxiusculum. The plant genus Acanthophyllumis one of the natural sources rich in nonionic surface active agents known as saponins. Sol-gel method as one of the most common techniques widely used in nano-field was applied to synthesize the titanium dioxide nanop...

Ammonium carbonate and ammonium sulfate have been proposed and used as two new fuels for synthesizing gamma alumina nanoparticles. The prepared samples have been characterized by X-ray diffraction (XRD), 2 N  adsorption (BET) and Transmission electron microscopy (TEM). A comparison has been made between the properties of the nanoparticles synthesized by these two fuels and other conventio...

In order to evaluate the adsorption potential of multi-walled carbon nanotubes (MWCNTs) for benzene, toluene and xylenes (BTX), the adsorption capacities of benzene and toluene on two different MWCNTs were measured using a gas-chromatography (GC) and then compared with each other. Fourier transform infrared (FTIR) was employed to investigate the presence of f...

CO2 reforming of methane (CRM) over unpromoted and potassium promoted Ni/Al2O3 catalysts was studied. The catalysts were prepared by impregnation method and characterized by X-ray diffraction (XRD), N2 adsorption (BET), temperature programmed reduction (TPR), temperature programmed oxidation (TPO) and scanning electron microscope (SEM) techniques. The obtained results showed that addition of K2...

Utilization of active and stable catalyst could have enormous advantages in industrial application of biogas reforming. In order to achieve this goal, the effects of Cu and Co as promoters were investigated over physical-chemical properties of Ni/Al2O3-ZrO2 catalyst in reforming of biogas. The sequential impregnation was used for preparation of catalysts. The catalysts were characterized using ...

In the present study, the gamma alumina (γ-Al2O3) nano powders have been prepared with addition of 1%mol Co using an aqueous sol-gel method at lower temperature than the pure gamma alumina. The synthesis process accomplished by partial hydrolysis of the aqueous solution of metallic ions Al3+ and Co2+, with ammonia. The Al(NO3)3.9H2O and Co(NO3)2.6H2O salts were used as cations sources. The obta...
