Abstract: A process for the manufacture of a solid phosphoric acid catalyst. A siliceous adsorbent is admixed with a polyphosphoric acid. The mixture is heated at an elevated temperature and thereafter extruded. High activity - high strength extrudate particles are produced by drying the extrudate first in a steam atmosphere and then in a dry air atmosphere.
