Abstract

Catalyst material (I) for Fischer-Tropsch (F-T) processes contains active carbon (II). Process for the prodn. of an Fe-based catalyst (I) comprises adding 1-80 wt.% (II) (w.r.t. amt. of Fe) to one of the catalyst precursors at any stage before extrusion. (I) is useful for the low-temp. variant of the F-T process, esp. as a solid-bed catalyst; amt. of (II) is 1-80 (pref. 1-50, esp. 1-20, e.g. 5-10) wt.% w.r.t. Fe, and (II) is uniformly distributed in (I); at least 50 (pref. at least 75, esp. at least 90) wt.% of the particles of (II) are smaller than 100 microns, pref. with at least 90 wt.% smaller than 45 microns, or the same proportion is in the size range 850-1200 microns; (II) is produced from pinewood, tanniferous acacia or coconut shells, and is preactivated with steam or mineral acid. USE/ADVANTAGE - (I) is useful as an F-T catalyst (part of main claim). A process is claimed for the prodn. of hydrocarbon waxes with improved colour, by contacting a suitable synthesis gas with (I) in a solid-bed reactor at elevated temp. and pressure; paraffin wax obtd. by this process is claimed as such. Catalyst (I) gives wax with a high Saybolt no. (pref. at least 20) directly, without the need for subsequent hydrogenation.
