Catalytic decomposition of natural gas has been opted as an alternative route for hydrogen production. Nickel- and Cobalt-based bimetallic catalysts over alumina support were prepared by the co-precipitation method for the investigation of hydrogen...
Effect of calcination temperature on Co-based catalysts was studied in order to evaluate the modifications in structural and catalytic properties for catalytic reforming of CH4 with CO2. In this regard, two sets of mono (i.e., CeO2 and ZrO2) and...
Methane is the most stable hydrocarbon and the highest component of natural gas. The occurrence of vast resources of natural gas promotes the catalytic decomposition of methane to produce hydrogen and valuable carbon. Hydrogen is an excellent energy...
Bimetallic catalysts, containing 5 wt% Ni + 5 wt% Co supported on γ-Al2O3 combined with different amounts of Sr promoter ranging from 0 to 1 wt%, for dry reforming reaction were prepared by the impregnation method. The dry reforming reaction was...
In this study, two series of Ni-based nanocatalysts were synthesized successfully by the polyol and surfactant-assisted methods and subsequently tested for hydrogen production from CO2–CH4 reforming. Surfactant-assisted catalysts were prepared by...
γ-Al2O3 supported Ni-Mn bimetallic catalysts for CO2 reforming of methane were prepared by impregnation method. The reforming reactions were conducted at 500–700 °C and atmospheric pressure using CO2/CH4/N2 with feed ratio of 17/17/2, at total flow...
Nano nickel catalysts supported over nano sized oxide powders (CeO2, ZrO2 and Al2O3) were prepared by the polyol method in ethylene glycol (EG) medium with polyvinylpyrrolidone (PVP) as a nucleation-protective agent. The activities of the prepared...
The nature of support and type of active metal affect catalytic performance. In this work, the effect of using La2O3 as promoter and support for Ni/γ-Al2O3 catalysts in dry reforming of methane was investigated. The reforming reactions were carried...

Dry reforming of methane (CH4) with carbon dioxide (CO2) catalysts produces synthesis gas at atmospheric pressure. Synthesis gas is important feed stock to chemical and petrochemical industries to produce chemicals such as methanol and ammonia. It...
Dry reforming of methane (DRM) is an environment friendly process since it utilizes two major greenhouse gases (CH4 and CO2) to produce valuable syngas. Polyol process was adopted to prepare nano supported (Al2O3, ZrO2 and CeO2) Ni based nano...
