I think carbonisation is the word, the end result is charcoal.
Carbon monoxide is produced when a fuel is burning with an insufficient oxygen supply.
The easiest way to purchase a charcoal filter is online. Some online places that supply charcoal filters include Amazon.com, EBay, and Google. Many pet stores also supply charcoal filters.
Charcoal burns quite well as a fuel, it just needs an air supply

Carbon monoxide is produced when you are trying to produce Carbon dioxide but have too little Oxygen. Basically (Quite an un-scientific explanation) burning with too little air or oxygen. The formation also has to do with a double covalent bond.
Prepositions would include "for" or more rarely "in."NOTE THAT THE WORD "to" following insufficient is normally part of an infinitive verb, not a preposition. E.g. The supply was insufficient to meet the demand.
