“…The degree of conversion in WGS reaction with this catalyst reaches 79.9%, which is remarkably high when compared to the 5% conversion with the catalyst on the basis of r (see line 2) and 9% conversion with the catalyst obtained using RuCI3, see line 10. So, the activity of the catalyst obtained with Ru3(CO)~2 as a ruthenium precursor and iron oxide support prepared from/5-FeOOH is 9 times greater than those for samples prepared with RuCI3 [4]. A small amount of basic admixtures, sodium, potassium or rubidium salts, introduced in the support leads to a further increase in activity of the catalysts especially when prepared via ~-FeOOH.…”

“…All rights reserve(t our earlier work [4], we have shown that a modification of the supports with small amounts of potassium, rubidium and cesium salts, in combination with the use of RuCI3, leads to stable Ru/Fe203 catalysts highly active in WGS reaction. Their activity was observed to depend on the kind of support and its modification.…”

“…Table 1 gives the measured activities of Ru/FeO3 catalysts containing 0.5 wt.% of Ru and obtained by deposition of Ru3(CO)12 on the calcination products of or-and 5-FeOOH modified by alkali metal salts at a molar ratio of Ru : alkali metal = 1:5. For the sake of comparison, these values are referred to the activities of the catalysts obtained with RuC13 [4]. Particularly interesting is the increase of activity of the Ru/Fe203 catalyst obtained by deposition of Ru3(CO),2 on the product of 5-FeOOH calcination.…”

A study was undertaken to determine the activity of ruthenium catalysts, obtained by deposition of Ru3(CO)t~ on products of iron oxide-hydroxide calcination modified with alkali metals, in the water-gas shift reaction. The activity depends on the kind of starting iron support, the ruthenium precursor and the amount of alkali metal salts. The most active were the catalysts obtained by deposition of Ru3(CO)x2 on calcination products of 5-FeOOH, both modified and unmodified with alkali metal salts, and of ct-FeOOH modified with alkali metal salts.

This review reports the recent research results of solid oxide fuel cells using biogas (typical composition, 60% CH 4 40% CO 2 ), reforming of CH 4 with CO 2 (CH 4 + CO 2 ¼ 2CO + 2H 2 ) and shift reaction of CO with H 2 O (CO + H 2 O ¼ H 2 + CO 2 ). Solid oxide fuel cells using dense yttria-stabilized zirconia and gadolinium-doped ceria electrolytes were operated with biogas containing CH 4 of 763 vol % at 630875°C. A maximum power density of 20160 mW/cm 2 was measured and this value was 1/101/3 of that for the cells with a H 2 fuel. The reforming of CH 4 with CO 2 proceeds over a Ni-based catalyst at 700900°C to produce a H 2 CO fuel. The carbon deposition due to the pyrolysis of CH 4 as a parallel reaction is suppressed by addition of second phase such as K 2 O or Ru to Ni catalyst. Electrochemical reforming of CH 4 with CO 2 using a porous Gd-doped ceria (GDC) cell is an attractive process to produce a H 2 CO fuel at 400800°C. The supplied CO 2 is changed to CO and O 2¹ ions by the reaction with electrons at the cathode (CO 2 + 2e . Furthermore, shift reaction of reformed gas with H 2 O vapor proceeded to produce a H 2 fuel using a porous GDC electrochemical cell with Co 2 O 3 catalyst at 400500°C.
