                      project AMAZING (Additive Manufacturing for Zero
                      emissionInnovative Green Chemistry) directly addresses this
                      by replacing large scale hightemperature cracking processes

                      thermocatalytic activation of alkanes to produce chemical
                      building blocks allowing significantreduction in the CO 2
                      emissions associated with energy intensive cracking
                      reactions.Thecore of the cell assembly is a ceramic membrane
                      made from mixed proton andelectron conducting La 6 x WO 12
                      δ To increase the electronic conductivity of the materialMo
                      as doping element is used to form La 6 x W 0.8 Mo 0.2 O 12
                      δ (LWO Mo20). The powder isin house produced and the
                      particle size, specific surface area and chemical
                      compositionis determined before the ceramic layers are
                      formed. Therefore, three differentfabrication techniques are
                      used in this work. The first one is sequential tape casting
                      andlamination to fabricate an asymmetric structure of a
                      dense m embrane layer (thickness25 µm) and a porous support
                      (thickness 500 µm). Furthermore 3D printingtechniques are
                      implemented to achieve defined support structures. Firstly,
                      acombination of tape casting and material extrusion ( is
                      introduced, where thesupport structure is printed directly
                      on a tape cast membrane layer. This techniqueallows a good
                      membrane quality but suffers during the co firing of the
                      final layers.Secondly, a pure 3D printing approach is
                      introduced, which utilizes 3D screen print ing.With this
                      technique both, membrane and support layer, are formed
                      subsequently in onemachine allowing good membrane quality
                      and precise support structures.Afterco firing all membrane
                      components undergo a quality testing procedure,
                      whichincludes He leakage determination and white light
                      topography. The next step is thejoining of the ceramic
                      membrane into a metal frame to form a membrane module,
                      whichcan easily be built in a test reactor and quickly
                      exchanged for multiple tests. The joiningprocedure takes
                      place in a furnace at 850 °C applying load on the sealing
                      area. Glasssealant is used to connect the ceramic and metal
                      part. After joining, another He leakagetest is performed to
                      assure the joining quality. With this procedure large
                      amounts oflab scale membrane modules can be fabricated for
                      further performance tests.},
