Hi folks, 
I am currently working on a reactor network to simulate the gasification of char. I want to create reactors, where the solid coal reacts with the surrounding gas. Therefore i need a yaml file containing the surface reactions. Is there a tutorial somewhere that includes features like reactions between 2 phases?

Thanks in advance,
Magdalena Krainz

For coal, I remember there was a chemkin format mechanism for coal gasification which included char reactions. But the mechanism is proprietary to chemkin and I would doubt they would be ready to share it unless you are a customer. 

CRECK maybe has coal mechanisms in chemkin format, you would need to convert them to a yaml format. https://github.com/CRECKMODELING/Kinetic-Mechanisms/tree/main/Solid-Phase/Coal

Best,
Omkar
