Abstract

The reaction of ethene, CO and H<sub>2</sub> on NiMo sulfide catalysts at 240-290 °C and at 1 MPa gives ethane, diethyl ketone, propyl ethyl ketone, propanal and diethyl sulfide (DES). The support (carbon, alumina, magnesia and zirconia) influenced the activity of catalysts and the ratio between oxygenated and sulfur products. The carbon supported catalyst was the most active, producing the lowest proportion of DES. The overall oxo selectivity was practically constant in a broad range of ethene conversion. Selectivity into the formation of diethyl ketone increased by lowering the reaction temperature and H<sub>2</sub>S concentration in the feed. A selectivity of about 25% into diethyl ketone was achieved with a feed containing 0.4% H<sub>2</sub>S at 240 °C.
