Abstract
A modified alumina catalyst support is prepared by mixing a Solution A containing alkali, a Solution B containing a salt of a modifying metal of Group 111A, other than aluminium, or V111 other than a platinum group metal, of the Periodic Table, and a Solution C containing a aluminium salt, to form a precipitate, ageing the precipitate, separating the precipitate from the supernatant liquor and calcining the precipitate. A platinum group metal may be added to the support and the resulting catalyst is suitable for catalyzing hydrocarbon conversation processes, particularly catalytic reforming.
