**4.3 Material selection and design**

Thermal plasma is a new disruptive technology, recently demonstrated in the labscale and pilot-scale studies [46]. Therefore, there is still a need to conduct further studies on the type of materials that can be used for constructing the reactor, electrodes, pipes and joints. While the temperature of the plasma reactor can locally reach *Green and Sustainable Chemical Looping Plasma Process for Ammonia and Hydrogen Production DOI: http://dx.doi.org/10.5772/intechopen.104095*

10,000 K [47], the bulk gas can reach a temperature up to 2000-3000 K. This requires a comprehensive study on material constraint and a material selection considering erosion, corrosion, and transient studies aiming at measuring tear and wear occurring inside the plasma reactor.

#### **4.4 Prototyping the reactors**

To the best of the authors' knowledge, this process is novel and there is no processing plant fabricated or constructed for ammonia/hydrogen production via thermal plasma plant. Hence, once kinetics studies are conducted, with the knowledge developed during material selection and design, prototypes can be constructed to measure the real-time efficiency, and performance of the 3CLAP process. In addition, there is further potential for other metals to be utilised in the process, thereby blending aluminium with other metals is another viable option to improve the real-life performance of the reactors.
