The corrosion behaviour of four different alumina-forming austenitic model alloys (Fe-Cr-Al-Ni based) in oxygen-containing molten Pb at 600 and 650 °C has been investigated. A thin protective oxide layer is formed on all after 2000 h °C, whereas increasing the temperature to accelerates oxidation promotes dissolution attack. Only one composition with minor additions Y Nb low Ni concentration sh...

This work studies the influence of introducing a CO2 adsorbent in bimetallic catalytic fixed bed reactor. The catalyst is lab-made Fe-Ni allow (2.5:7.5 wt/wt) supported on gamma alumina. Two adsorbents were tested this study, lab made CaO and Na2O (10

The electroless deposition method was used to prepare Ni-based nanocomposite coatings, this approach represents an alternate way of having coatings on the different substrates. Most previous literatures subject and work deals with a study effect process conditions and, Bath composition microstructure at macroscale Ni-Al2O3 composite coatings. Though, step structure bath are little, present aims...

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...
