چکیده

The structure and performance of promoted Ni/Al2O3 with Cu via thermocatalytic decomposition (TCD) CH4 mixture (2% CH3OH) were studied. Mesoporous Cat-1 Cat-2 synthesized by the impregnation method. corresponding peaks nickel oxide copper in XRD showed presence oxides as a mixed alloy calcined catalyst. Temperature program reduction (TPR) that enhanced reducibility catalyst peak shifted toward lower temperature due to interaction strength metal particles support. 10% on drastically improved catalytic exhibited 68% conversion, endured its activity for 6 h compared Cat-1, which deactivated after 4 h. investigation spent carbon various forms obtained by-product TCD, including graphene fiber (GF), nanofiber (CNF), multi-wall nanofibers (MWCNFs) active sites following kinds growth mechanisms. D G bands Raman spectroscopy confirmed amorphous crystalline morphology deposited carbon.

Decomposition of hydrogen peroxide in a catalytic fluidized-bed reactor

The decomposition of H2O2 by a novel supported g-FeOOH catalyst was performed in a continuous fluidized-bed reactor. This catalyst has been successfully used in the treatment of organic contaminants with H2O2 in our previous work. In this study, we attempted to determine the effects of pH, H2O2 concentration, and catalyst concentration on the decomposition of H2O2. An approach, we regarded this...

Methanol decomposition using a catalytic reactor with electric discharge

Methanol decomposition using a catalytic reactor with electric discharges was investigated in the present study. The methanol conversion at 190 °C was 58.0%; however, the methanol conversion increased by 65.9% under the electric discharge. An electric discharge produces high energy electrons with sufficient energy to break a C-OH bond.

Catalytic Decomposition of Ammonia over Bimetallic CuO/CeO2 Nanoparticle Catalyst

The oxidation of ammonia to nitrogen by selective catalytic oxidation (NH3-SCO) over a bimetallic CuO/CeO2 nanoparticle catalyst at temperatures between 423 and 673K. A bimetallic CuO/CeO2 nanoparticle catalyst was prepared by co-precipitation method at molar ratio of 6:4. This study also considers how the concentration of influent NH3 (C0 = 800 ppm), the space velocity (GHSV = 92000/hr), the r...

Modeling and Simulation a Catalytic Fixed Bed Reactor to Produce Ethyl Benzene from Ethanol

Ethyl benzene used increasingly each year is the raw material of producing styrene monomer. This substanceis produced from benzene alkylation with ethylene or ethanol, depending on the availability and cost of rawmaterials. In this study benzene alkylation in the presence of ethanol in a catalytic fixed bed reactor inthree states of isotherm, adiabatic and non-isotherm-non-adiabatic is mathemat...
