Abstract
An extruded silica-alumina base catalyst is prepared by cogelling a silica sol solution containing aluminum and having a pH in the range of about 1-3. The cogelled silica-alumina is peptized to form an extrudable dough and may be mulled with Group VI-B and Group VIII metals to prepare a denitrification catalyst extrudable composition.
