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

Die comprising metal printed parts for the extrusion of moulded bodies

A process for producing an aqueous polymer solution, including: (a) providing a hydrated polymer that has been prepared by aqueous solution polymerisation of ethylenically unsaturated monomers, which hydrated polymer contains at least 10% by weight active polymer; (b) cutting the hydrated polymer by subjecting the hydrated polymer to at least one cutting stage containing at least one stream of aqueous liquid at a pressure of at least 150 bar to reduce the size of the hydrated polymer; and (c) dissolving the hydrated polymer in an aqueous liquid so as to obtain an aqueous polymer solution. An apparatus for producing an aqueous polymer solution.
