South temperature/carbon conversion

Over AU/AI2O3 the reaction between carbon monoxide and nitric oxide is severely inhibited by oxygen, and this unfortunately militates against the promise of its use for three-way conversion at low temperature. Nevertheless the effectiveness of a gold-containing catalyst developed at the Anglo-American Research Laboratories in South Africa has been demonstrated (Figure 11.3).42 It consisted of 1% Au/CoOx in admixture with... 

The first products resulting from this unit were in line with expectations based on the 100 b/d pilot plant operations. The reactor feed had a 31.3 API gravity South Louisiana reduced crude including a slurry oil recycle (17 API) rate of 4% on feed. The reactor temperature was 910° F. with the cat to oil ratio of 3.5. A 53.5 vol% conversion was obtained with Super Filtrol natural clay catalyst. The regenerator operated at 1052° F., the spent catalyst containing 1.6 wt% carbon while the regenerated catalyst was reduced to 0.5 wt%. Flue gas excess oxygen was 4.4 wt%. The observed yields for PCLA 1 are recorded in Table II.
