Method of Heating a Foam-Based Catalyst Bed
- Tuesday, 01 December 2009
Although the light-off temperature of
most catalysts is only a few hundred
degrees Celsius, the electrically heated
foam is able to achieve temperatures of
1,200 ºC. Lower temperatures are achievable
by supplying less electrical power to
the foam. Furthermore, because of the
foam’s open-cell structure, the catalyst
can be applied either directly to the
foam ligaments or in the form of a catalyst-
containing washcoat. This innovation
would be very useful for heterogeneous
catalysis where elevated temperatures are
needed to drive the reaction.
