The present invention describes a modified catalyst support in the form of particles of titanium dioxide having a volume median diameter in the range of 100 [mu] m to 1000 [mu] m, modified with one or more refractory oxides of a metal selected from zirconium, lanthanum, cerium, yttrium and neodymium, wherein the total refractory oxide content of the modified catalyst support is in the range of 0.1 wt% to 15 wt%, and the modified catalyst support has a pore volume in the range of 0.2 cm3/g to 0.6 cm3/g and an average pore size in the range of 30 nm to 60 nm. The modified catalyst supporter can be used for preparing a cobalt Fischer-Tropsch catalyst suitable for a fixed bed process. 本发明描述了一种体积中值直径在100μm至1000μm的范围内的二氧化钛颗粒形式的改性催化剂担体，该改性催化剂担体用选自锆、镧、铈、钇和钕的金属的一种或多种难熔氧化物改性，其中该改性催化剂担体的总难熔氧化物含量在0.1重量％至15重量％的范围内，并且该改性催化剂担体具有在0.2cm3/g至0.6cm3/g的范围内的孔容积和在30nm至60nm的范围内的平均孔径。该改性催化剂担体可用于制备适用于固定床工艺的钴费托催化剂。
