Subsequently is
introduced a propane gas duct by the air entrance to the reactor, to
create a flame inside the combustion chamber, then the vacuum
pump was turned on and the propane gas feed is removed. In less
than 15 min or when the temperature in pyrolysis zone (TC 2 and
TC 3) reaches 573 K the ignition step is completed and the record of
the profile of reactor temperatures and the gases flow starts.
