The project has resulted in a new film-like material that can separate by-products from the plastic production process and use them further.

It is well known that many plastics are made from ethylene and propylene, which belong to a group of unsaturated hydrocarbons called olefins. The feedstocks for these olefins are alkanes, such as light gasoline and naphtha, which are decomposed in a thermal process called steam cracking that occurs within the reactor.
During this process, hydrogen is released as a by-product, which must be laboriously separated for further use. The steam cracking process requires temperatures of up to 850 degrees Celsius produced by burning fossil fuels, making olefin production one of the most energy-intensive industrial processes that generate large amounts of emissions.
The AMAZING project is seeking to make the production of olefins more sustainable by developing a membrane-based process that separates the products of the reaction process from the cracking process and makes them available for further use. To further reduce emissions from the process, the reactors used in the AMAZING project will be heated by electricity provided by renewable energy sources.
Based on the number of steam cracking facilities currently in operation, the project’s process in Germany alone could save about 5.2 terawatt hours (TWh) of energy and 3,871 kilotons (kt) of carbon dioxide annually. Subsequently, the developed process can provide significant cost savings for electric systems compared to fuel heating systems.

Project partners will use3D printingto create and integrate ceramic membranes into reactors that enable the production of olefins and the simultaneous separation of pure hydrogen.3D printingThe membrane has a catalytic function that lowers the dehydrogenation temperature of alkanes, thereby separating hydrogen from product gases.
by deploying3D printingTo create membranes, their surface, microstructure and chemical composition can be tailored specifically for the cracking process. Various properties of the membrane can be tuned and optimized to improve the efficiency of the process, such as how well the membrane transports the separated hydrogen and how effectively the membrane supports the separation of hydrogen from alkanes.
3D printingMembrane prototypes and assemblies can also be made easy to test, and if the technology proves to be suitable for large-scale use and economically viable, the partners are confident3D printingMembrane modules can be produced on a commercial scale in the future.

In addition to improving energy efficiency, the proposed method also produces directly usable hydrogen, which was previously only used thermally as a by-product of the cracking process. To achieve this, the partners will create a hybrid conductive film (MIEC) that removes hydrogen and thus can be used as an energy carrier or as a chemical feedstock.
The two processes proposed by the project also show promise for applications beyond olefin production, such as the use of sustainably produced hydrogen in other industrial processes or the transport sector to reduce emissions, thereby supporting Europe’s goal of achieving climate neutrality by 2050 .
