Wood gasification can happen in as little as 350 c BUT, happens much better around the 800c mark.

In my totally uneducated view, the methane,, acetone, etc. are NOT even in the wood yet as you heat it slowly. You have to get up to the temperatures where the "destructive distillation" occurs to break down existing chemicals into those other components that you list. You need temps high enough to disassemble and maybe recombine things like the cellulose and the famous "pyrolignous acids". I'm thinking well over 100°C to even start most of those processes.
