The reduction behavior of nickel oxide (NiO) and zirconia (Zr) doped NiO (Zr/NiO) was investigated using temperature programmed reduction (TPR) using carbon monoxide (CO) as a reductant and then characterized using X-ray diffraction (XRD), nitrogen absorp... see more

This study investigates the potential of bimetal impregnated catalysts supported on activated carbon derived from biomass for Selective Catalytic Reduction (SCR) of Nitrogen Oxides (NOx) with ammonia (NH3). The bimetal catalysts, Copper-Manganese (Cu-Mn) ... see more

Nickel catalysts, containing 6% (w/w) of nickel, have been prepared using TiO2, Al2O3 and mixture of TiO2-Al2O3 (1:9). The catalysts were used for CO2 conversion into methane. The characteristics of catalysts were studied by determination of its specific ... see more

This paper investigates the oxidative dehydrogenation of ethane to produce ethylene at low temperatures (500 °C) in metallic structured substrates. To check this point, the FeCrAlloy® monoliths with different channel sizes (289–2360 cpsi) we... see more

A novel gas-phase electrocatalytic system based on a low-temperature proton exchange membrane (Sterion) was developed for the gas-phase electrocatalytic conversion of CO2 to liquid fuels. This system achieved gas-phase electrocatalytic reduction of CO2 at... see more

The climate of the Earth is changing. The Earth’s temperature is projected to maintain its upward trend in the next few decades. Temperature and precipitation are two very important factors affecting crop yields, especially in arid and semi-arid reg... see more

 Gross wastes of the steel industry were evaluated as catalyst for the reduction of nitrous oxide. The wastes were obtained from steel mill residues (MS), lamination (LA), quenching (QC) and blast furnace powder (BF) and characterized by X-ray fluore... see more

The dry reforming reaction of methane comes as a promising process of syngas and hydrogen. Nickel catalysts on Al2O3 and SiO2 were synthesized by sol-gel method, with metalic load of 8% weight. The catalysts were characterized by temperature programmed re... see more

Cu/Nb2O5 catalysts were modified by the incorporation of MgO or K2O (support acidity reducer) and Ni (a facilitator of the bond break C-C) to be used in the ethanol reforming in bench-scale unit with catalytic bed of 7 g at 573 K, varying the space veloci... see more
