Stirring biomass is not easy to do in a vertical reactor. A line of reactors has been developed by Parr Instrument Company to function horizontally.
Horizontal reactors enable researchers to mix bio feed stock and other cellulosic materials such as:
- corn stover
- sugar cane
- wood pulp
- wood chips
In the horizontal position, the internal stirrers tumble the material rather than try to stir it with a standard vertical stirrer. These custom reactors are secured vertically for loading and then safely tilted horizontally for stirring. They can also be designed to be operated in both a horizontal and vertical position.
||The one liter reactor pictured at the left can be oriented vertically for loading or tilted horizontally for stirring. A heavy-duty stirring motor and double anchor stirrers are used. Another option would be to tilt upside down for discharge. A 4848 Controller monitors the system pressure and controls the temperature and stirring speed. A flexible mantle heater (not pictured) is used to obtain temperatures up to 350 °C. Maximum pressure is 1900 psig for this system.
||The 4578 Pressure Reaction System shown at center left is a 1.8L, fixed head reactor mounted on a floor stand and rated for temperatures up to 500 °C with a maximum pressure of 5000 psig. These custom reactors are secured vertically for loading and then safely tilted horizontally for stirring.
||The horizontal function is also available on our large capacity reactor systems. The reactor shown on the left has a five gallon capacity and is used for stirring horizontally. Pneumatic controls on the left can tilt the system upright to allow the bottom drain valve to be opened. The product is filtered and collected in the lower heated sample collection vessel. This system is used for producing synthetic fabric from biomass as an alternative to a petroleum-based process.
