Abstract
A process for the preparation of a zirconia precursor comprises contacting a solution of an acidic zirconium compound with a solution of a basic zirconium compound to form a gel. A shapable dough may be formed by rendering the zirconia precursor shapable, for example by drying the zirconia precursor or combining the zirconia precursor with a solid filler. The shapable dough may be shaped, for example by extrusion, to form a shaped zirconia precursor, which in turn may be dried and calcined to form shaped zirconia particles. The shapable dough may be prepared so as to comprise a source for a catalytically active component, in which case the shaped zirconia particles may be used directly as a catalyst. A source of a catalytically active component may be deposited on the shaped zirconia particles to yield a finished catalyst.
