Bio-Fuels and Alternative Fuels Research Systems
P
arr Instrument Company manufactures
non-stirred vessels for the decomposition
of biomass in ammonia and steam. Parr stirred
reactors, including a new horizontal reactor
technology, have been designed for research
processes that include hydrogenation, isomeriza-
tion, and metathesis reactions. In addition, fully
customizable continuous-flow tubular reactor
systems have been developed with continuous
reactant feed and product handling capabilities.
The above photo illustrates a complete pilot
scale plant used for hydrogenating feedstock
that originates from a proprietary fermentation
process. The system is used to develop and
optimize the process conditions necessary for
a much larger demonstration-scale system,
ultimately leading to full-scale production of
renewable fuels.
The system is comprised of five major
subsystems: from left to right, a gas and liquid
feed system, the jacketed tubular reactor module
including a reactant pre-heater and circulating
bath, product recovery and backpressure control,
an auto-sampler and a Parr 4871 Control System
(not pictured). The system is completely auto-
mated and includes an auto-sampling subsystem
that periodically samples the reactor output
stream in order to accurately monitor product
quality.
Custom Reactor Systems like the above Bio-Fuels Research System are a product of collaboration between the researchers
and the Engineers at Parr Instrument Company.
