In recent years active carbon (AC) supported metal-containing CO reacting catalysts are
studied. In the literature few works concerning catalytic conversion changes of the chemical
nature CM, however, are published at its modifying. The aim of this work is the CO
conversion catalytic investigation of a CM modified by Co/Fe/Ni.
A CM activated carbons, KAU and SCN, was used as the starting material. AC KAU (raw
material apricot stone) had cleanly carbon surface. Obtained of nitrogen containing resin CA
SCN had a nitrogen compound carbon surface. For modifying CM by Co/Fe/Ni metals had
been used acid solutions of their nitrate salts. The last ones were impregnated carbons KAU,
and SCN within 48 hours. In the further samples dried at 100С, warmed up in argon at 450С
and reduced in hydrogen in current of 1 hour at 600С. The covering of a surface CM metal
made 5 % wt. accordingly (in recalculation on metal).
The catalytic tests were carried out in flow fixed-bed quartz reactor. The studied reaction
mixture contained: 1 vol.% СО, 1 vol.% О 2 , 98 vol.% Нe. The analysis of reaction products
was carried out by on-line gas chromatograph with conductivity detector.
