Carbon-Monoxide Hydrogenation Over Metal Loaded Aluminophosphates

This paper describes the preparation of molybdenum, cobalt and iron loaded ALP04- 5 catalysts via adsorption and decomposition of the corresponding carbonyl complexes. Mo (CO) 6 and Fe (CO) are adsorbed within the ALP04- 5 pores, and 30-50% of the transition metal is retained on subsequent activation. Co2 (CO)s adsorbs, and decomposes also on the external surface. The molybdenum-
and iron-loaded ALP04 - 5 catalysts show activities and selectivities in carbon monoxide hydrogenation similar to the corresponding zeolites. Broader product distributions from the cobalt loaded A1PO4- 5 are consistent with external loading, but this catalyst does not maintain a stable activity.
