ABSTRACT:

According to patents from Shell a mechanical mixture of a cobalt catalyst and a Cu/Zn/Al sub 2 O sub 3 has been used successfully in a fixed-bed reactor to carry out Fischer-Tropsch synthesis with a low H sub 2 /CO feed. In our slurry reactor, however, we encounter substantial deactivation with the Cu/Zn/Al sub 2 O sub 3 catalyst when combined with a Co catalyst. A detailed and critical literature review was made of water-gas-shift catalysts. Activation procedures are critically important.  Reports of poor performance by other researchers seem to stem from use of too high reduction temperatures and/or improper procedures for catalyst preparation. We have been using commercial catalysts and recommended activation procedures. The slow deactivation we observed may be associated in some way with the use of a slurry reactor instead of fixed bed. 55  refs., 13 figs., 9 tabs. (ERA citation 14:012509)
