ABSTRACT "A method of preparing a catalyst" The invention relates to catalysts. In service, catalysts must not only be capable of selectively catalysing chemical reactions but also be mechanically robust to withstand normal process conditions and possible plant operation such as catalyst regeneration following, e.g., catalyst poisoning. Commercial catalysts have therefore to satisfy the dual requirement of high stable activity and long service life. The various catalysts produced by existing techniques, such as impregnation of a high surface area preformed carrier or the pelletizing of co-precipitated materials, in fact represent compromises between strength, activity and stability. The object of the invention is to provide an improved catalyst, the objective being met by a method of preparing a catalyst comprising precipitating a catalytically active component together with appropriate spacers and/or promoters within the pores of a preformed, low surface area, ceramic matrix, to establish therein a substantially stable, high-area active phase.
