Abstract
Non-supported, fixed bed catalyst tablets made by spray drying a slurry of the components into microspheres followed by tabletting the microspheres under high pressure in apparatus such as punch and die sets. The catalysts formed according to the process of this invention have better catalytic performance and/or crush strength than do conventionally made pellets such as extrudates.
