Abstract: The invention relates to additive manufacturing an object for separation and/or conversion of a substance from a liquid by guiding the liquid therethrough. A build material is printed in a predetermined arrangement in order to form a three-dimensional monolith structure. The build material includes an active/activated material configured to interact with the liquid. The three-dimensional monolith structure is printed to define an inlet, an outlet and a plurality of flow channels arranged between the inlet and the outlet of the structure, wherein the plurality of flow channels define meandering flow paths between the inlet and the outlet, wherein at least one mixing region is provided within the structure, wherein the at least one mixing region is in fluid connection with at least a set of the plurality of flow channels such as to allow mixing of the liquid guided through said set of the plurality of flow channels.

Abstract: A process prepares an oxygen carrier for a chemical looping process including providing a material A having a first transition metal and/or an oxide of the first transition metal. The first transition metal is selected from chemical element groups 6-11 of the Periodic System. Material A is subjected to a reaction with H2 to reduce the first transition metal and/or oxide to form a reduced material B. Material B is treated with a salt solution of a second transition metal selected to have a standard reduction potential larger than the first transition metal. A portion of the first transition metal in the reduced material B is replaced by the second transition metal. A molar ratio of the first transition metal with respect to the second transition metal in material B ranges between 2:1 and 100:1. An oxygen carrier is obtained with the method and is regenerated using steam.
