Abstract:
During the period 1990-1993 research was being performed on the synthesisand characterisation of perovskite and hexa-aluminate catalytic monolithic
systems for the combustion of methane at high temperatures. The development
of these systems was aimed at high temperature and high flow conditions
existing in e.g. gas turbines. Ceramic foam carriers were used as a support
for the catalytic materials. As catalytic materials the perovskite
La0.25Sr0.75MnO3 and the hexa-aluminate BaMnAl11O19 appeared to
combine a high stability with a satisfactory activity. For coating purposes a
special preparation procedure was developed, during which the catalytic
materials were formed in situ. The catalytic activity and physicochemical
stability under laboratory testing conditions appeared to be satisfactory
