Copper-Promoted Cobalt/Titania Nanorod Catalyst for CO Hydrogenation to Hydrocarbons

The effect of Cu on cobalt/titania nanorod (Co/TNR) catalysts for the promotion carbon monoxide (CO) hydrogenation to hydrocarbons was investigated. Varying amounts (1.5–6.0 wt%) were loaded onto base Co/TNR catalyst using deposition–precipitation method. Characterization by X-ray diffraction (XRD) revealed that particles well dispersed over catalysts. Characterizations temperature-programmed desorption hydrogen (H2-TPD) and (CO-TPD) reduction in (H2-TPR) proved promoter its bimetal with Co, where containing generally showed a significant improvement comparison not promoter. CO H2 adsorption capacities reducibility optimal 1.5% (1.5Cu-Co/TNR). This aligns catalytic activity performance all catalysts, 1.5Cu-Co/TNR exhibited best performance, yielding 16.8% conversion 57.7% C5+ hydrocarbon selectivity at 240 ? 5 bar.
