Abstract: A method for producing a three-dimensional porous catalyst monolith of stacked catalyst fibers, comprising the following steps: a) Preparing a suspension paste in a liquid diluent of a reforming catalyst, and which suspension can furthermore comprise a binder material, all particles in the suspension having an average particle size in the range of from 0.5 to 500 μm, b) extruding the paste of step a) through one or more nozzles to form fibers, and depositing the extruded fibers to form a three-dimensional porous catalyst monolith precursor, c) drying the porous catalyst monolith precursor to remove the liquid diluent, d) calcining the porous catalyst monolith precursor to form the porous catalyst monolith.

Abstract: The invention relates to a die (10) for the extrusion of catalyst molding, catalyst support molding, or adsorbent molding (60) in flow direction (32) of an extrudable composition from an entry side (12) to a discharge side (14) of the die comprising a shell (56) and comprising one or more channel-formers (18) which are displacers of the extrudable composition and which extend in flow direction of the extrudable composition, wherein the channel-formers (18) have been metal-printed.
It is preferable that this is free from cavities for receiving extrudable composition which extend at right angles to the flow direction (32) of the extrudable composition, and that this is free from connections running at right angles from channel-formers (18) to the interior side wall (22) of the die (10).
The invention further relates to a process for the production, by means of 3D metal printing, of a metal-printed die (10) for the extrusion of catalyst moldings/support moldings (60).

Abstract: The invention relates to a shaped catalyst body in the form of a tetralobe having four circular through-passages, with the midpoints of the through-passages forming a square and the spacings between in each case two adjacent through-passages being from 0.8 to 1.2 times the thickness of the outer walls of the through-passages. The shaped catalyst body is used for the oxidation of S02 to S03.

Abstract: A computer-implemented method (110) for designing at least one shaped body (112), a computer-implemented method (138) for designing a manufacturing process for manufacturing at least one shaped body (112), a designing system (152) for designing at least one shaped body (112) and a manufacture-designing system for designing a manufacturing process for manufacturing at least one shaped body (112). The computer-implemented method (110) for designing at least one shaped body (112) comprises: a) retrieving, by using at least one interface (154), at least one set of target criteria for the shaped body (112); b) defining, by using at least one geometry defining unit (156), at least one seed geometry for the shaped body (112); c) generating, by using at least one parameter generating unit (158), a set of parameters comprising at least one geometry parameter of the seed geometry; d) simulating, by using at least one simulation unit (160), the shaped body by varying values of the set of parameters and by corn-paring simulated criteria for these values with the set of target criteria, thereby generating at least one adapted set of parameters for which the target criteria are fulfilled at least within predetermined tolerances; and e) determining, by using at least one lead candidate geometry defining unit (162), at least one lead candidate geometry of the at least one shaped body (112) from the adapted set of parameters.
