Abstract
Process for producing shaped bodies of catalysts, catalyst supports or adsorbents by microextrusion in which a pasty extrusion composition of a shaped body precursor material is extruded through a movable microextrusion nozzle and through movement of the microextrusion nozzle a shaped body precursor is constructed in layerwise fashion and the shaped body precursor is subsequently subjected to a thermal treatment, wherein for construction of each shaped body precursor the pasty extrusion composition is simultaneously extruded through a plurality of microextrusion nozzles.

A process for producing shaped bodies of catalysts, catalyst supports or adsorbents by microextrusion in which a pasty extrusion composition of a shaped body precursor material is extruded through a movable microextrusion nozzle and through movement of the microextrusion nozzle a shaped body precursor is constructed in layerwise fashion and the shaped body precursor is subsequently subjected to a thermal treatment, wherein for construction of each shaped body precursor the pasty extrusion composition is simultaneously extruded through a plurality of microextrusion nozzles arranged in a row in an extrusion head, wherein for layerwise construction of a shaped body precursor an extrusion head is rotatable horizontally by 90° and moved in spatial directions perpendicular to one another or the layerwise construction of a shaped body precursor is carried out by at least two extrusion heads moved in spatial directions perpendicular to one another.
A process for producing shaped bodies of catalysts, catalyst supports or adsorbents comprising:
- microextruding a pasty extrusion composition of a shaped body precursor material through a movable microextrusion nozzle;
- constructing a shaped body precursor in layerwise fashion through movement of the microextrusion nozzle;
- and
- subsequently subjecting the shaped body precursor to a thermal treatment, wherein for construction of each shaped body precursor the pasty extrusion composition is simultaneously extruded through a plurality of microextrusion nozzles arranged in a row in an extrusion head, wherein for layerwise construction of a shaped body precursor an extrusion head is rotatable horizontally by 90° and moved in spatial directions perpendicular to one another or the layerwise construction of a shaped body precursor is carried out by at least two extrusion heads moved in spatial directions perpendicular to one another.
