Abstract
A method of preparing a catalyst support is described comprising washing a precipitated metal oxide material with water and/or an aqueous solution of acid and/or base such that contaminant levels in said precipitated metal oxide are reduced. The method may be applied to precipitated alumina materials to reduce contaminants selected from sulphur, chlorine, Group 1 A and Group 2A metals. The catalyst supports may be used to prepare catalysts for the Fischer-Tropsch synthesis of hydrocarbons.
