The effects of alkali promoters on the activity and selectivity of Co/NaY catalyst have been investigated. The catalysts were prepared by impregnating NaY with aqueous solutions of alkali compounds and a benzene solution of Co2(CO)8. Hydrocarbon synthesis was studied in a flow reactor under the reaction conditions : temperature = 200∼250℃, space velocity = 120∼160hr-1, pressure = 1 atm, H2/CO = 1. As the basicity of alkali promoter increases, the olefin selectivity, probability of chain growth, and CO2 formation increase and methane formation decreases. The activity of CO hydrogenation increases with the pH of alkali solutions.
