PROCESS FOR THE PRODUCTION OF PELLETS OF METAL POWDER AS CATALYSTS

The invention relates to a process and an apparatus for the production of pellets of metal powder, more particularly pellets of highly active metal powder, for example Raney catalysts. According to the invention, no inert gas atmosphere is required to avoid oxidation of the metal powder. The pellets...

More Information
Summary:The invention relates to a process and an apparatus for the production of pellets of metal powder, more particularly pellets of highly active metal powder, for example Raney catalysts. According to the invention, no inert gas atmosphere is required to avoid oxidation of the metal powder. The pellets are produced by direct press molding of the suspension in a wet environment. The invention also relates to the use of catalyst pellets thus produced in trickle-phase and gas-phase processes.
