Abstract Herein, the promotion effect of only 0.3 wt% indium on 3% Ni/Al2O3 and Ni/CeO2-Al2O3 catalysts prepared by deposition-precipitation over a commercial alumina CeO2-modified support was studied. Catalyst characterization XRD, TPR, XPS, TEM, CO-DRIFTS performed. The catalytic properties were investigated coke formation analyzed under temperature ramped CH4-decomposition in Dry Reforming M...

An arc-sprayed amorphous Al–Ti–Ni coating on S355 structural steel was processed by laser remelting (LR) at powers of 600, 800, and 1000 W. The surface-cross-sectional morphologies, chemical element distributions, and phase compositions of the as-obtained Al–Ti–Ni coatings were analyzed using a scanning electron microscope (SEM), energy-dispersive spectrometer (EDS), and X-ray diffractometer (X...

Abstract Ethanol steam reforming was studied over Ni supported catalysts. The effects of support (Al 2 O 3 , Al –ZnO, and –CeO ), metal loading, catalyst activation method, steam-to-ethanol molar feed ratio were investigated. properties catalysts by N physisorption, TPD-CO X-ray diffraction, temperature programmed reduction. After activity tests, the analyzed TOC analysis. catalytic measurement...

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...

A novel two-stage pyrolysis-plasma/catalysis process has been developed for hydrogen production from waste biomass. Investigation into; the comparison of biopolymers, cellulose and lignin; effect Mg, Co, Ce, Cu, Fe Ni as promoter metals added to a Ni-Al2O3 catalyst; influence catalyst support material in relation was carried out. The combination plasma catalysis produced highest total gas yield...

Electrochemical coating processes are significantly affected by applied magnetic fields due to the generation of electromagnetic forces. The present research work has been undertaken to study the effect of coating parameters such as current density and alumina concentration on the characteristics of Ni-Al2O3 composite coating under static magnetic field. Ni-Al2O3 composite coating was applied o...
