Popis:	Resistance towards attrition, sufficient activity at end-of-run and high selectivity to desired products are some of the requirements for a slurry Fischer–Tropsch catalyst. We have found that modifying an alumina support by 2-valent metals, including magnesium, nickel and zinc, followed by high temperature firing, results in superior mechanical and ‘chemical attrition’ (dissolution) resistance of the catalyst. Further, a sufficiently high surface area is being stabilized. The catalyst performance has been verified in a long term test in a semi-commercial plant, including very good wax separation and high wax purity. Combined with appropriate process conditions, stable long-term operation of the catalyst is secured.
