Patent ID: 8003564

Claim:
A process for the preparation of a Fischer-Tropsch catalyst or catalyst precursor, comprising the steps of: (a) admixing: (i) a catalytically active metal or metal compound with cobalt, iron and/or ruthenium as catalytically active metal; (ii) a carrier material, said carrier material being a refractory metal oxide; (iii) a liquid selected from the group consisting of water, ammonia, alcohols, ketones, aldehydes, aromatic solvents, and mixtures of the aforesaid liquids; (iv) a gluing agent selected from the group consisting of ammonia, ammonia-releasing compounds, ammonium compounds, amino acids, quaternary ammonium hydroxides, a carboxylic acid, a carboxylic acid derivative, a poly-carboxylic acid, and mixtures thereof, all optionally with other functional groups being present in the carbon chains; and (v) optionally one or more promoters, and/or one or more co-catalysts; (b) forming the mixture of step (a); and (c) drying the product of step (b) for more than 15 hours, at a temperature up to 30° C. to form the catalyst or catalyst precursor and not calcining the catalyst or catalyst precursor.
