The activated carbon which removes ethylene
The activated carbon which is impregnated palladium can remove
ethylene gas by catalytic reaction.
C2H4　CH3CHO
Pd2+　Pd　0
Catalysis reaction mechanism
It is a characteristic to use the oxidation catalysis of
the activated carbon for the re-oxidation of palladium
reduced to its elements by olefine.
As for the oxidation catalyst function of the activated
carbon, the reaction rate improves in the presence of
water remarkably.
Therefore the most suitable
catalyst is it-based for reaction under the saturation
humidity such as the freshness maintenance.
Activated carbon　O*/Activated carbon
Ethylene concentration (ppm)
Test method
Pour a catalyst activated carbon, ethylene, water in a glass ampoule of contents
product 190ml ; of the ethylene remaining concentration pass, and is the
measurement by a change at time.
Reaction time (hr)
Moisture=20wt% , Addition ethylene=2ml
Temprature = 30℃
△：T-E　1g，□：T-E　2g，○：T-E　2g　5℃
It is reaction rate of about 0.2 - 0.3ml/hr (ethylene) at catalyst activated
carbon 1g. The result that reaction rate becomes slow was provided, but
5℃ are thought to be caused by the fact that adsorption performance
becomes high in low temperature in comparison with 30℃.
