dc.description.abstract | An experimen
tal evaluation of a microchannel reactor was completed to assess the reactor performance
for the catalytic decomposition of vaporised formic acid
(FA) for H2
production. Initially,
X-ray
powder diffraction (XRD),
elemental mapping using SEM
-
EDS and BET sur
face area measurements
were done to characterise
the commercial Au/Al2O3 catalyst
.
The reactor was evaluated using pure
(99.99%) and diluted (50/50 vol.%) FA at reactor temperatures of 250
–
350°C and inlet vapour flow
rates of 12
–
48
mL.min
-
1
.
Satisfactory r
eactor performance was demonstrated at 350°C as near
-
equilibrium FA conversion (>98%) was obtained for all flow rates investigated. The best operating
point was identified as 350°C and 48 mL.min-1
(pure FA feed) with a H2
yield of 68.7%.
At these
condition
s
the reactor performed well in comparison to conventional systems, achieving a H2
production rate of
11.8 NL.gcat -1.h-1. This paper therefore highlights important considerations for
ongoing design and development of microchannel reactors for the decomposition of FA for H2
production | en_US |
