Generally, the term 'destructive distillation' is used to refer to the processing of certain organic materials along with limited amounts of oxygen and certain reagents, solvents, or catalysts such as phenols and steam. It can also be used to denote the processing of organic material in an environment void of air (pyrolysis in the absence of air).
