Slurry phase Fischer-Tropsch synthesis was conducted on precipitated iron-silicon catalysts. The affect of copper promotion on the activity and selectivity of carbon monoxide, hydrogen and syngas activated catalysts is presented. High activity and stability have been obtained for potassium promoted catalysts when operating at 270{degrees}C; however, it has been found that promotion with potassium and copper is essential to obtaining good activity in a wax producing mode at 230{degrees}C. Promotion with copper is critical to achieving good activity when pretreating catalysts with hydrogen or with syngas at high pressure. XRD and Mossbauer data indicate that copper facilitates the reduction of iron oxide to metallic iron and iron carbides during hydrogen and syngas pretreatments.
