 # Reaction and recombination of the molecules, and triggering of chain reactions through free radicals
-The pyrolysis process and the formation of products can be controlled to a certain extend via different temperature ranges and reaction times as well as by utilising reactive gases, liquids, catalysts, alternative forms of heat application (e.g. via microwaves or plasma), and a variety of [[reactor designs]].
+The pyrolysis process and the formation of products can be controlled to a certain extend via different temperature ranges and reaction times as well as by utilising reactive gases, liquids, catalysts, alternative forms of heat application (e.g. via microwaves or plasma), and a variety of [[reactor designs]]. Depending on the residence time and temperature as well as different technical reaction environments the pyrolysis can be categorised under diffferent terms as follows.
+=== Categorisation according residence time and temperature ===
+* Fast pyrolysis
+* Intermediate pyrolysis
+* Slow pyrolysis (charring, torrefaction)
+=== Categorisation according technical reaction environment ===
+Depending on these factors the pyrolysis technology can be divided into different categories as follows:
+* Catalytic cracking
+** One-step process
+** Two-step process
+* Hydrocracking
+* Thermal cracking
+* Thermal depolymerisation?
