AB  - In the present investigation, nanostructured Ni/Al2O3 catalyst supported on
reticulated alumina-mullite foam was synthesized by aerosol assisted coating. The
synthesis process was optimized from the technological and economic aspect.
Ultrasonically generated NiCl2 water solutions were applied to α-Al2O3-mullite foam
in a tubular quartz reactor. The first procedure involved calcination at 773 K for 1 h
in order to obtain NiO/Al2O3 precursor. The second procedure involved drying at
473 K for 1 h without oxidation. The activation step involved hydrogen reduction at
633 K. The effectiveness of the low-temperature hydrogen reduction was
compared for those systems. It was determined that the samples were reduced in
a high degree at 633 K for 90 minutes and the hydrogen flow rate of 20L/h.
However, SEM of calcined sample shows presence of agglomerates. The samples
reduced from NiCl2 had no agglomerates and the metallic phase was
homogeneously dispersed compared to the samples obtained by NiO reduction.
The most probable reason for the effective low-temperature reduction was the
formation of thin coatings consisted of oxide and chloride precursors for the
catalytically active components. XRD analyse of the samples after the reduction at
633 K for 90 minutes showed only metallic nickel, alumina and mullite phases.
Residual phases of NiO and NiCl2, as well as NiAl2O4, were not detected. The
production process can be simplified and economically more favourable by
avoiding the calcination step.
