A lab-scale biomass fast pyrolysis system was designed and constructed based on an auger reactor concept. The design features two intermeshing augers that mix biomass with a heated bulk solid material that serves as a heat transfer medium. A literature review, engineering design process, and shake-down testing procedure was included as part of the system development.
Laboratory scale pyrolysis plant can help you asses the raw material profitability, reaction time, reaction temperature, mass balance, oil/coke/gas yields, catalyst efficiency, oil quality etc. Before you establish commercial pyrolysis plant, it is a wise idea to test the raw material in the laboratory scale plant.
A wide range of reactors have been used on a laboratory scale for the plastic pyrolysis process. The reactor set-up in this research is a batch reactor. A common variant between the batch and semi-batch operations is the vacuum, which causes the reduction of temperature of the reaction to take place inside the Borosil round bottom flask.

Lab tests in combination with different modeling approaches aim at the improvement of critical components such as the pyrolysis reactor and product recovery. A technical lab scale plant (10 kg/h feed capacity) is used for the development of the process by testing new plant components, operation variations, and measurement systems.
This process is called pyrolysis, and it is marked by darkening in the color of the bean. At some point after pyrolysis sets in, but before the bean is terminally burned, the moment of truth arrives for the roastmaster, because the pyrolysis, or volatilization, of the coffee essence must be stopped at precisely the right moment to obtain the .
The outlet line is connected to vacuum to help suction the pyrolysis vapor out of the system and minimize secondary reactions that consume the bio-oil.Once the vapors leave the reactor, they go through a series of heat exchangers (condensers) in which the vapors are cooled and liquid bio-oil is collected.
