Highly Efficient Synthesis of C.sub.2.sup.+ Oxygenates from CO Hydrogenation Over Rh-Mn-Li/SiO.sub.2 Catalyst: The Effect of TiO.sub.2 Promoter

The effect of titanium promotion on the catalytic performance of Rh-Mn-Li catalyst supported on PVP-modified SiO.sub.2 for C.sub.2.sup.+ oxygenates synthesis from CO hydrogenation was investigated. The highest selectivity toward C.sub.2.sup.+ oxygenates (51.3%) was achieved over the RML/0.5Ti/SiO.su...

Description
Summary:The effect of titanium promotion on the catalytic performance of Rh-Mn-Li catalyst supported on PVP-modified SiO.sub.2 for C.sub.2.sup.+ oxygenates synthesis from CO hydrogenation was investigated. The highest selectivity toward C.sub.2.sup.+ oxygenates (51.3%) was achieved over the RML/0.5Ti/SiO.sub.2 catalyst. Characterization results indicates that the addition of Ti promotes the adsorption of geminal CO and the formation of Rh.sup.+, which is favorable for the CO insertion into metal-CH.sub.x band, and finally increases the selectivity of C.sub.2.sup.+ oxygenates.
