Glass-ceramic materials were developed from gabbro including MgO and Al2O3 additives. Heat treatments for phase transformation from glassy matrix to glass-ceramic were carried out at 1000 ◦C for 3 h. X-ray di raction studies conducted on the glass-ceramic samples revealed that the phases formed in the glass-ceramics were cordierite, anorthite, diopsitic augite, forsterite and andesine. Glass an...

Structured catalysts for the simultaneous removal of soot and nitrogen oxides were prepared by means of coating cordierite monoliths with alumina-based suspensions containing Cu, Co or Fe and Cs as the catalytically active phase. Textural and chemical properties of the coated monoliths were determined by means of N2-physisorption, SEM and temperature programmed reduction. Their activity in the ...

Light-off of the partial oxidation of methane to synthesis gas on a rhodiumcoated cordierite honeycomb monolith at short contact times is studied experimentally and numerically. The objective of this investigation is a better understanding of transient processes in catalytic oxidation reactors. The numerical simulation predicts the time-dependent solid-temperature distribution of the entire rea...

This study presents the development of a method for washcoating Ni/boehmite gels, prepared by sol–gel process, onto surface commercial ceramic monolith. Indeed, cordierite monolith in honeycomb shape was used as substrate Ni/Al2O3 deposition. An experimental assembly made order to apply coating on surface. Different suspensions were with various viscosities, and multiple parameters tested withd...
