Reducing gas atmosphere containing CO and H2 as processing gasses is commonly used in the
metal processing industry for heat treatment of special metals. For the production of reducing
atmosphere conventionally are employed nickel catalysts on various ceramic supports. Since
the process takes place at high temperature, thermal stability and textural properties of catalysts
are of particular interest. In this work magnesia supported nickel catalysts were synthesized.
The catalyst synthesis consisted of single or successive impregnations with nitrate precursor
salts of nickel and modifiers (Al, Ca and Mg), followed by thermal catalyst activation. Nickel:-
modifier molar ratio was 10:1.The solid to liquid mass ratio was 1:3. The concentration of Ni in
impregnation solution varied from 1.0 to 3.0 moldm-3. Mercury intrusion porosimetry was used
for textural characterization since the synthesized catalysts were predominantly macroporous.
The impregnation led to decrease of total po...re volume, broadening and shifting of pore size distribution curve towards smaller pores. These changes were enhanced with the increase of initial
concentration of Ni solution and number of successive impregnations as well as the nature of
modifier. The Ni-catalyst modified with Al showed the best textural properties.
