Dear Jay, Thanks for the reminder that this may not be as easy as running our kitchen meth labs (Ha! Ha!, DEA; I made a little joke!)
Seriously: I'd hate to see anyone do harm just for innocently sailing off into "uncharted territory". Most of this territory is well charted; the reactions are predictable. The overhead to ensure both success and safety is substantial, but it's best not avoided. Pressure vessels? Catalyzed reactions? Be certain that you have a textbook knowledge of these concepts. Then pour-on the Radium!

Nickel based Fischer Tropsch catalysts promote the hydrogenation (-H) and methanization (-CH3) chain termination steps, therefore there is a tendency for lower HC chains and methane production (ie: lower alpha). From what I understand, these also favor lower temperatures which in turn counteract the high wax formation of iron at lower temperatures. However, cobalt is more frequently used, possibly because of disposal cost. I once heard concern of side reactions consisting of nickel-carbon complexes which are bad news, and a haz mat nightmare. Possible nickel-carbon complexes include nickel carbonyls which are commonly known as 'liquid death' has anyone else heard of this happening as a side reaction in FT?
