3D-printing of hierarchical porous ZSM-5: The importance of the binder system

摘要

Intelligent catalyst design can help to further improve the stability, selectivity and activity of existing adsorbents and catalysts. The use of 3D-printing for manufacturing of structured supports is a useful tool for the rapid prototyping of different compositions and different architectures of structured adsorbents and catalysts. Despite their proven advantages in use as adsorbents and catalytic supports with respect to heat and mass transfer and pressure drop, coated structured supports still encompass some such as loading of catalyst. To overcome these drawbacks, in this work, 3D-printed monoliths were manufactured directly using ZSM-5 as active material to build up the structured adsorbent or catalyst. As sufficient mechanical strength of such structures is crucial for the use in industry, this was one of the main focus points in this work. A combined binary binder system is shown to be advantageous for the adjustment of the mechanical properties of the self-supporting structured material. Furthermore, the chemical properties can be adjusted according to the binder used. (C) 2017 Elsevier Ltd. All rights reserved.
