Cyclonic Fast Pryolysis

Flash pyrolysis that is carried out in a cyclone can be categorized as cyclonic flash pyrolysis; this type of pyrolysis tries to optimize the bio-oil quality by minimizing the amount of char and particulate matter that is contained within the bio-oil product. Tubular reactors can be used to perform flash pyrolysis, however an agglomeration of these materials can build up within the reactor, which not only will affect the product quality, but this will hinder the input feed into the reactor as this problems continues. When carrying this process out in a cyclone, a swirling motion can be utilized within the reactor that allows for the gases to have constant circular movement within the vessel, which will lower the potential of the particulate matter to be produced and the tendency for caking as well. Application of this centrifugal force within the actual reactor can be very beneficial for process operation. Particulate matter will in fact form, however the amount and size of these particles can be reduced greatly; cyclone separators can be used to help separate these particles from the product gas as well.
