Abstract
An alumina catalyst support substantially free of thermal skrinkage and having desirable physical properties is disclosed which is obtained by heating an alumina extrudate in a zone heated by direct fire to 1800.degree.-2600.degree. F. with combustion gases therein until less than 5% shrinkage when exposed to 1800.degree. F. for 24 hours is obtained. Promoted supports as effective shrinkfree catalysts and the method therefor are also disclosed.
