To identify the synergistic action of differently prepared Ni-ZrO2 phase boundaries in methane dry reforming, we compared an “inverse” near-surface intermetallic NiZr catalyst precursor with respective bulk-intermetallic NixZry material and a supported catalyst. In all three cases, stable high reforming activity enhanced anticoking properties can be assigned to presence extended boundaries, whi...

Internal dry reforming of methane is envisaged as a possibility to reduce on capital and operation costs biogas fuelled solid oxide fuel cells (SOFCs) system by using the CO2 present in biogas. Due internal reforming, requirement for upgrading becomes obsolete, thereby simplifying complexity increasing its technology readiness level. However, impurities prevailing such H2S have been reported li...

Our goal in this paper is the description and analysis of new findings and results on membrane reactors and catalytic reactors/heterogeneous processors for the steam reforming reactions of methane, natural gas, and methanol for use in power generation systems and fuel cells. The current communication continues this research by giving emphasis in the so-called “Improved Reaction” and “ReformingF...

This work investigates the effect of Potassium promoter and calcination temperature on catalytic activity in dry reforming methane reaction compares performance Ni, Co, Fe–Al2O3 trimetallic catalysts with reference Ni–Al2O3. Although higher was achieved Ni–Al2O3, resulted a more favorable CO/H2 ratio considerably better coke resistance. Higher led to increase formation which caused sintering ca...

Combustion of conventional energy sources produces pollutants such as SOx, NOx, and CO; the use hydrogen methane can eliminate these harmful emissions. In fuel cell technology other uses, must be refined by extracting from methane/hydrogen combination, produced via dry or steam reforming. This study investigates adsorption separation capabilities recently discovered zeolite-templated carbons (Z...

This work initially focuses on developing a computational fluid dynamics (CFD) model of an industrialscale steam methane reforming reactor (reforming tube) used to produce hydrogen. Subsequently, we design and evaluate three different feedback control schemes to drive the area-weighted average hydrogen mole fraction measured at the reforming tube outlet ( x̄H outlet 2 ) to a desired set-point va...

Macro-mesoporous alumina, calcined at different temperatures (from 400 to 800 °C), were tested in dry reforming of methane reaction under plasma discharge a fixed deposited power (P = 8 W) with ratio CO2/CH4 2. Besides alumina materials, the one possessing lowest surface area (72 m2 g?1) exhibited highest activity: Methane conversion reaches 31.3 % against 23.4, 22.6 and 26.8 for 400, 600 °C, r...
