Can objects (such as wood) reach high temperatures without burning?

I read a bit about active charcoal and how it's produced, so I got interested in the following:

Does the wood only get heated (600-900 C) without necessarily burning? because burning wood creates ash, whilst active charcoal is from charcoal, which is not the same.

Or is it inevitable for a combustible object to burn at high temperatures?'

Edit: Additional info: To create active charcoal, wood is placed in an isolated fireproof container inside a hot system/fire with desired temperatures of 600-900 C for 4-6 hours.

For something to burn you need oxygen. If you were to keep wood at low oxygen and high temperatures, you'd get charcoal. Same goes for other materials. They'd breakdown or melt at high temperatures, but not burn because of the lack of oxygen.
