PROCESS FOR THE PREPARATION OF HYDROCARBONS A process for the preparation of hydrocarbons by catalytic reaction of carbon monoxide with hydrogen wherein the feed is contacted at elevated temperature and pressure with a catalyst comprising 3-60 pbw cobalt, 0.1-100 pbw zirconium, titanium, chromium and/or ruthenium per 100 pbw of carrier, which catalyst is in the form of a fixed bed and has an external surface area SE and wherein together with the feed a hydrocarbon-containing liquid boiling above 100 .degree.C is passed through the catalyst in a downward direction at such a superficial liquid flow velocity VS at the inlet of the bed that the product Vs x SE is larger than 1. |
