>The dimethyl siloxane type of polymer will confine hydrogen
since oxygen carbon and silicon all keep hydrogen from escaping.
No, that is incorrect. As Steve High says, this material was never in the
reactor.
This is a high temperature polymer adhesive, yet it will not confine
hydrogen at extreme high temperature, even if was in the reactor (which it
wasn’t). You will see a complete de-polymerization at about 400 C.
* The Lithium Aluminum Hydride was not added to the fuel mix for its
good looks. The Hydride had a definite purpose.
This is a well-known hydrogen storage material. Hydrogen is apparently
required for startup of this reactor. That is its purpose.
According to Wiki, LiAlH4 contains 10.6 wt% hydrogen, and … Due to its high
thermodynamic stability this requires temperatures in excess of 400°C to
release hydrogen, which is not considered feasible for transportation
purposes. Above 400 C, the hydrogen is completely gone from the LiAlH4 - and
from the reactor itself. In a 30 day run, approximately 29 days and 22 hours
will be hydrogen free. The reason for the initial hydrogen seems to be to
startup the reaction,
