CH3NO2 ADDITION TO CO HYDROGENATION OVER A RU/KY CATALYST

CH3NO2 addition to CO hydrogenation over Ru/KY led to the formation of partially dehydrogenated CHx groups, which became indistinguishable from CHx groups derived from CO hydrogenation. Random reaction of these groups provided hydrocarbon formation along the same reaction pathway that normally occurs during CO hydrogenation over Ru/KY. The additional CHx groups from CH3NO2 enhanced the rates of chain initiation and propagation to similar extents, leading to increases in the rates of formation of C2+ hydrocarbons. Some of these CHx groups were further dehydrogenated and formed surface carbon, resulting in the incorporation of some carbon from CH3NO2 into CO2, an increase the rate of catalyst deactivation, and suppression of secondary reactions on the support. © 1991.
