Thermal decomposition of propane near 300 C.

[dcopps]

My Subject says it all. I am finding a lot on thermal decomposition at higher temperatures, but nothing in the 300 C range. I am trying to determine the durability of propane as a working fluid.

What else is present other than propane?

Longer chain hydrocarbons are resistant to coking to at least 300 C, so propane should be as well.

Propane will be the only chemical present. It may have exposure to SS metal surfaces as well.

We dry propane with mole sieves and regenerate the beds at 500F, no problem.
