Novel catalytic combustion system for #ammonia
… catalytic combustion … is regarded as a promising technique for decreasing emissions from hydrocarbon-based fuels and was actively studied for use in gas turbines, boilers, and jet engines in the 1980s. This system has many advantages over conventional noncatalytic combustion, as NOx emission is greatly diminished by the low operating temperatures and high efficiency can be achieved through stable combustion. More recently, RenCat (a start-up company in Denmark) has been commercializing technology to decompose NH3 into H2 for use in fuel cells. … NH3 decomposition (cracking) reaction is endothermic, whereas NH3 combustion reaction is exothermic. Therefore, … NH3 decomposition can be effectively promoted by the heat produced from NH3 combustion. Therefore, to establish the further potentiality of NH3 fuel, it is desirable to develop a novel catalyst with high thermal stab...
