This work is devoted to a preliminary study on the feasibility of cata
lytic combustion for syngas fuelled gas turbines equipped with Mn-subs
tituted hexaaluminate catalysts. Results of catalytic activity tests o
n combustion of CO-H-2 over BaMn1Al11O19 and La0.8Sr0.2Mn1Al11O19 are
reported and analyzed by means of a mathematical model of the catalyst
section of a hybrid combustor. Experimental activity levels are shown
to be close to the operating requirements of the combustor.
