Abstract: |
The
development of an efficient process for ammonia synthesis is a goal that has
been long sought after; therefore, the application of an absorptive reactor
for ammonia synthesis is important since it allows the reaction to occur
under milder conditions. In the adjacent-coupling absorptive reactor, absorbent
particles are positioned downstream the fixed ammonia synthesis catalyst bed.
This kind of absorptive reactor leads to the enhanced conversion of ammonia
synthesis under milder conditions, compared to the equivalent reactor used
without absorbent. Here, we present the transient backflow cell model (BCM)
to explain and analyse the phenomenon of
absorption-enhanced reaction. The transient BCM, based on the first principle
of mass balances, is developed to simulate that the backflow existing through
the absorptive reactor. As a reference, the transient cell model (CM) is also
implemented to simulate the absorptive reactor when assuming no existing
backflow existing. These two models demonstrated that backflow through the
absorptive reactor promotes the ammonia reaction conversion via two
mechanisms: longer residence time for reaction and faster reaction rate due
to the absorption of ammonia absorbed. |
