The invention provides a process for preparing a cobalt-containing catalyst precursor. The process includes calcining a loaded catalyst support comprising a silica (SiO) catalyst support supporting cobalt nitrate to convert the cobalt nitrate into cobalt oxide. The calcination includes heating the loaded catalyst support at a high heating rate, which does not fall below 10° C./minute, during at least a temperature range A. The temperature range A is from the lowest temperature at which calcination of the loaded catalyst support begins to 165° C. Gas flow is effected over the loaded catalyst support during at least the temperature range A. The catalyst precursor is reduced to obtain a Fischer-Tropsch catalyst.
