ABSTRACT:
Alumina-phosphorous powders can be extruded into catalysts supports having improved properties by the addition of up to 15% by weight of a polycarboxylic acid, containing 2-10 carbon atoms, based on the dry weight of the alumina-phosphorous powder prior to extrusion. The addition of the polycarboxylic acid also increases the extrusion rate.
