PROCESS FOR THE PREPARATION OF ALUMINA-BASED EXTRUDATES

摘要

A process for the preparation of an alumina-based extrudate suitable for use in the manufacture of a catalyst, comprises the steps of: i) preparing an extrudable mixture comprising an alumina precursor, a cobalt, iron or nickel source and a solvent; ii) extruding the mixture; and iii) drying the so-formed extrudate. The extrudable mixture may optionally comprise a promoter source. Alternatively, a promoter source may be deposited on the resulting extrudate. A catalyst is prepared by calcination of the resulting extrudate, which catalyst is useful in the preparation of hydrocarbons from methanol or a mixture of carbon monoxide and hydrogen.
