“…The conversion continued to decrease with time and reached 44% at 120 min as seen in figure 2. The negative effect of water on conversion was also observed by Snytnikov et al [19] over Pt/C and by Park et al [20] over Cu-Ce/ [15], which provides additional evidence indicating that support-metal interaction plays a crucial role and leads to different results even for relatively inert supports such as MgO and Al 2 O 3 . A similar trend was also observed in O 2 conversion over Pt-Co-Ce/MgO while there was no considerable difference in the selectivity for CO oxidation.…”

1.4 wt% Pt-1.25 wt% Co-1.25 wt% Ce catalyst on MgO support was prepared using incipient to wetness impregnation technique and tested in a micro-reactor flow system for the low temperature preferential oxidation of CO in hydrogen rich streams. 100% CO conversion was achieved at 130°C with a feed composition of 1.0% CO, 1.0% O 2 , 60% H 2 and He as balance at a space velocity of 24,000 cm 3 /g-h. The addition of 25% CO 2 did not affect the performance of the catalyst significantly, while 10% H 2 O in the feed decreased the activity. 100% CO conversion was obtained at 150°C in the presence of 25% CO 2 and 10% H 2 O in the feed.

“…The negative effect of CO 2 and H 2 O seems to be cumulative. The decrease in both activity and selectivity of the PrOx catalysts, due to the competitive adsorption of CO, CO 2 and H 2 O on the catalyst surface has been broadly reported [33][34][35][36]. Again a decrease on the O 2 activation rate due to the competition of oxygen with water and carbon dioxide should be considered.…”

“…Analogously in the presence of CO-co-feeding during anisole HDO at 150 • C over Mo 2 C under atmospheric pressure benzene formation was suppressed and completely recovered after CO-co-feed was stopped [44]. Pt/C is active for water gas shift reaction forming carbon dioxide during HDO [84]. …”

Hydrodeoxygenation (HDO) of bio-oils, lignin and their model compounds is summarized in this review. The main emphasis is put on elucidating the reaction network, catalyst stability and time-on-stream behavior, in order to better understand the prerequisite for industrial utilization of biomass in HDO to produce fuels and chemicals. The results have shown that more oxygenated feedstock, selection of temperature and pressure as well as presence of certain catalyst poisons or co-feed have a prominent role in the HDO of real biomass. Theoretical considerations, such as density function theory (DFT) calculations, were also considered, giving scientific background for the further development of HDO of real biomass.
