The general objective of obtaining an emitting catalytic device at lab scale able to resist to max. temperatures of 1400°C was pursued by means of the following activities: a.Selection of suitable candidate catalyst formulations for methanol combustion with sufficient activity and extremely high thermal stability (among supported perovskites, hexaaluminates, pyrophosphates or other classes of refractory materials) b.Preparation of selected catalysts, via several alternative preparation methods; catalyst engineering via deposition of active phases over structured supports to fit in a lab-scale test rig c.Catalyst characterization: chemical, physical, superficial, morphological properties of fresh and thermally aged catalyst samples Catalytic combustion tests with premixed methanol - air feed run either under controlled pseudo-isothermal conditions and/or self-sustained high temperature operating conditions respectively in order to acquire information on the intrinsic activity (such as light-off temperatures, product selectivity, reaction kinetics) and to assess catalyst durability at high temperature and define operating maps
