Abstract: A three-dimensional porous catalyst, catalyst carrier or absorbent monolith of stacked strands of catalyst, catalyst carrier or absorbent material, composed of alternating layers of linear spaced-apart parallel strands, wherein the strands in alternating layers are oriented at an angle to one another, wherein the distance between inner spaced-apart parallel strands is larger than the distance between outer spaced-apart parallel strands in at least a part of the layers of the monolith.

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.

Abstract: A method and system for printing a three-dimensional porous structure (1). Interconnected filaments (2) are deposited in a predetermined arrangement in a plurality of stacked layers (11). The filaments (2) of the consecutive layers (11) are connected to one another to obtain the porous structure (1) with interconnected pores (15). The filaments are deposited in such a way that one or more preselected frangible regions (7) are formed in the arrangement of filaments (2). The one or more frangible regions (7) are connected to less-frangible regions (9) of the porous structure (1). The predetermined arrangement of interconnected filaments (2) is configured such that the one or more frangible regions (7) form structurally weakened zones of the porous structure (1) such that the porous structure (1) breaks along said one or more frangible regions (7) under influence of a load and/or a stress. The plurality of three- dimensional parts (10a) are releasable under influence of the load and/or stress.
