Types of Pyrolysis Reactors

There are several types of pyrolysis reactors used for producing bio-oil with the most common being fluidized-bed (bubbling and circulating), ablative, vacuum, entrained-bed, and auger reactors. For pyrolysis to be "fast," two key design parameters need to be considered: the reactor must allow high heat transfer to the biomass and residence time must be short. A slow heat transfer and longer residence time lead to large production of gaseous and solid fuels.
