CARBON-MONOXIDE HYDROGENATION OVER COBALT CATALYST IN A TUBE-WALL REACTOR .1. EXPERIMENTAL STUDIES

Effects of temperature (250-275-degrees-C). pressure (0.1-1.03 MPa) and feed gas exposure velocity (139-722-mu-m/s) were studied on carbon monoxide hydrogenation in a tube-wall reactor using plasma-sprayed cobalt catalyst. The specific catalytic activity and hydrocarbon selectivity increased with an increase in pressure and temperature and a decrease in the exposure velocity. The results showed that the formation of olefins especially ethylene and propylene was favored at low pressures, low temperatures and high exposure velocities. This catalyst was found to be selective for C5+ hydrocarbons (27-34 wt. %) at increased pressures (0.69-1.03 MPa).
